kevex saidAnother funny thing is, bisexuals can't even define what bisexuality is. All these supposed bisexuals give different versions: You discover it, you choose it, you are born with it, everyone is innately bisexual, monosexual people can become bisexual, you can be emotionally attracted to both genders, etc. Then what the fuck is it? Also, being gay and having sex with a woman and cumming inside of her or a drunk straight dude getting a blowjob from a guy =/= Bisexuality. I need evidence, not personal experiences or vague pseudo-scientific articles.
It seems the definition is clear: being attracted to more than one gender. But you're saying you don't know the cause? So you write it off because you want to see evidence?
You know that they haven't proven the cause for being gay yet, right? Every study that has been done has concluded with a theory, not a definitive answer. But thanks to Lady Gaga, "born this way" has become a popular saying among LGBT circles, so without having the research to back it up, people took it and ran with it. So you could argue the same thing about being gay, that it's not a real thing or is a choice made by individuals.
Also, bisexuality has been observed in the animal kingdom. Many animals that have been observed engaging in same-sex activity also engage in intercourse with the other sex. It's a rare
case to see an animal that refuses to engage with the opposite sex, but does happen, like with those gay penguins in SF.
