Why are studies always focusing on male homosexuality and not female homosexuality?

as a bisexual woman, yes, there are many more attractive women than men. but then again, im only attracted to certain types of men. yet most women can be found attractive. a womans body is just generally more attractive because curves are attractive...women can be almost any size or shape and look good. men...im only attracted to ones that have muscle. dont get me wrong, there are some men i find VERY attractive. but too fat, too skinny...its easy for men to fall into either category, though falling into the sexy category is a different story. also with the study on how many US men and women are gay/bisexual...that is probably wrong. many girls say they are bisexual or act like it, even to the point of kissing other girls, because men find it attractive. they dont actually like girls, they just think it will get them a man, so it is probably slightly less than 16%. as for men, its a lot harder for a man to come out. they face a lot more discrimination than women do, so the number is probably slightly higher than 5%. really, a womans sexuality is not plastic. they just know that men find it attractive when a woman is willing to be with another woman. lots of girls take advantage of that and say theyre bisexual because then they can get all the men they want, but if they have to kiss a girl to turn a guy on they can do that without weird looks. trust me, there is nothing more annoying than a straight girl pretending to like girls to get a guy. and it usually happens with drunk girls. its one thing to experiment, but a totally different thing to be fake about it when you KNOW you dont like girls. i mean really, does anybody like hanging out with someone who pretends to be their friend and talks bad behind their back? its the same idea, nobody likes a fake bisexual person.
