General

On paper, OP's main point is "correct" in the sense that you are technically on paper theoretically able to take a liking to more people. As has been discussed, this might not be 100% or anything by nature of human sexuality as a spectrum and personal tastes.

However, there was also mention of "competition for the person who likes him or her", which is definitely not true. In this case it's not even a matter of "personal preference in looks". There is definitely a stigma associated with any form of homosexuality or "deviant" behaviour by certain groups of thought. That being what it is, being bisexual doesn't necessarily open you up to the world as much as it makes you to subject of hate by a (sadly) large group of people. Expressing any form of sexuality other than heterosexuality is no easy task.

My last girlfriend was bi, she was sexually attracted to both males and females but she'd only date or be in relationships with guys.

[quote=SirKibbleX2]So would a bisexual person be interested in a shemale/ladyboy or is that taking it too far? And where do transvestites fit here? I still can't find a good answer to stop my confusion of bisexuals and pansexuals, and half of the answers I've seen seem to compare the two a lot more than contrast (and even say they are barely if at all different, so perhaps I don't have to be concerned about finding a difference). I also feel extremely ignorant typing this. (I've only seen 1 openly gay person where I live in this asian-hispanic adult conservative community (from when I was 0-18 years)).[/quote]

if by shemale/lady boy you mean born x/now y, then more than likely yes interest is highly possible. if you mean born x/dresses y, or transvestite/crossdresser, then, well, it's really up to personal preference (and i'd hate to leave you with that answer!). i'm not too well versed in pansexuality, but i do know they're all about it - male, female, them, and everything in between

try thinking of it this way: sexual orientation is based off one's romantic and sexual attraction to a certain "gender" and the qualities that embody said gender. for ex, the attraction between straight males to females is significantly rooted in female portrayal ('beautiful', elegant, obedient), just as female to male ('handsome', strong, dominant). this also applies to gays and lesbians - gays are attracted to men because of their masculine portrayal, while lesbians are attracted to females because of their femininity. bisexuals are into both roles of male and female.

transgenders are more affiliated with personal preference, not sexual orientation. transgenders are born either female or male, yet struggle with the gender identity they were assigned and eventually undergo his/her physical transformation. transgenders usually start by taking hormone dosages and eventually have full body surgery. there's no real catch here - just that they didn't personally identify themselves with how they were born and decided to do something about it (tons of trans don't even acknowledge their transition; they live day2day life as if they were always a boy or girl). by definition, transgenders are equally up for grabs as any born male or female by the straight/lesbian/gay community. however, it's more by personal preference people shy from them

transvestites are people who act and dress like the opposite sex without undergoing intense physical surgery. think crossdressers. besides pansexuals, i don't know where else they fall under in terms of sexual orientation preference. i'm also unsure what pronouns they use, but i'd guess they/them because they're physically male or female but portray the opposite

so we have our males (he/him) and females (she/her), and now we have our genderfluids (they/them). these people don't identify as male or female because they don't want to fill gender roles (female's beauty, elegance or male's handsomeness, dominance). i'd say they're the "third gender." according to the definition, bisexuals would not be interested in these people (they are neither male or female); however pansexuals would be.

straight <3 female* / male*
bisexuals <3 female* + male*
pansexuals <3 female + male + them + everything inbetween

*includes transgenders, the only rejection of him/her would be from personal preference
(sorry if this is hard to understand, this is my first time explaining over the internet in less than a few paragraphs)

Edit: to answer OP's question, uh, i think he has the right-ish idea. if the population was 50/50 male/female and 100% of the people was attractive: straight, gays, and lesbians are only attracted to 50%. bisexuals would be attracted to 100%.
unfortunately the world is full of ugly people, tastes vary, and there is an uneven distribution of male to female :<

by definition bisexuals are people who are attracted to both males and females.
would they be attracted to a transgender person?

it obviously depends on the bisexual himself/herself.

just like saying you're a straight guy doesn't mean you're going to be attracted to every single woman out there.

Does this mean OP's question is unanswerable?[/quote]

Well, OP's question isn't exactly logically sound.

Not considering specific statistics; the concept of attraction (both physical and cognitive) is far too large to address a question with a "black and white" base.

OP's question isn't unanswerable so much as incompatible with the actual concepts it addresses.

That said, it's worth noting that "black and white" logic is generally fallacious and invalid outside of a "yes or no" context. Even then, the validity is questionable at best.

A bisexual individual could technically be interested in a transexual, as it wouldn't necessarily deviate from the definition of "bisexual", however on an individual level, it'd be up to the person to decide whether they were interested in that sort of thing. Again, bisexuality should just be seen as a sort of general term for physical attraction between both sexes with no cognitive specifics taken into account.

Think of it like this. Biology is a science and so is Psychology. Despite some overlap in the fields (specifically neuroscience and evolutionary perspective psychology), each of them are still their own specific fields. However, they are also both sciences; "science" being used as a more general term.

Bisexual - General reference to attraction phenomena.
Pansexual - Specific type of attraction phenomena that overlaps into the category of "bisexuality".

really? I'm pretty confused with bisexual and pansexual then. Cause I just assumed ya know.. bi.. two. Or is there a 3rd genitalia that I'm totally unaware of.

I always thought trans was a 3rd category (like if you're gonna go be a girl you are still a dude no matter what, but now you look like a girl, it's now a mix. It's no longer one thing or another thing, you are a mix of the two making something that either side does and doesn't have).

Now, I don't pay much attention to LGBT(Q?) topics so I'm not completely doubting you guys, also no offense for the "3rd category" thing.[/quote]

Pansexuality can technically be viewed as a more pure/fluid form of bisexuality, so your assumption isn't entirely inaccurate. However, there are key differences to be noted between pansexuals and bisexuals. Pansexuals being that they primarily focus on the emotional interpersonal connection between the individuals, whereas bisexual is simply a way of describing being physically attracted to both males and females. Essentially, the difference is emotional v. physical roots in the attraction itself.

i.e.) Not all bisexuals are pansexuals, but all pansexuals could be classified as bisexuals.

This distinction is generally why you'll see questions in regards to sexual attraction only cover straight, gay, or bisexual.

when I said 100% of the population and 50% I meant like interested in both male and females or male or female in general not like specifically

No offense.[/quote]

well you're right, bisexuality is attraction towards males and females. from what i know, transgender isn't a third gender - it's just a gender role switch. the transgenders i'm familiar with hardly enjoy acknowledging their "switch" and are content with using their preferred pronouns of he/him and she/her.

you might be thinking of "gender fluid" people who use the preferred pronouns "they/them" - these people don't identify as male or female, thus segueing into more of a third gender than trans. i'm not sure if bisexuals are into gender fluidity (since they're not "male" or "female&quot, but i'd assume not

[quote=SirKibbleX2]They would not like trans.[/quote]

False.

It's not usually how I roll, but there's one transexual I know that I find attractive.

That said, the conditions of attraction can be rather vague; it's not exactly accurate to pin classifications on different phenoms of attraction between different identities, despite the fact that we still do it for practicality's sake.

[quote=SirKibbleX2]They would not like trans.[/quote]

untrue

transgender and sexual orientation have no immediate relationship. trans are x who identify as y, and sexual orientation is (more often than not) sexual/romantic attraction towards x or y. bisexuals are people sexually/romantically attracted to x and y, categories that transgenders fall under

bisexual means you're attracted to both male and female genders so no they are not attracted to the whole population. That's pansexuals because they are attracted to all genders and sexualities.

An average person who is bi will probably like about as many people as the average person who is straight.

@mateocl it can be black and white.

Anyways OP to answer your question, no.

Are you straight? If so: are you attracted to every girl you see walk down the street? No of course not. You have your own select prefrences And therefore arent attracted to 50% of the population. Also sexuality isn't black and white as above stated.

If you view sexuality more as a spectrum than straight, bi or gay, that might help you. o.o
