DTF, convince one of your guy friends to have sex with you, just wake up one day and say "I'm going to be gay" and see how that experience is for you. You won't ever be able to force yourself to do that because you just plain aren't gay. If you would like to disprove me then film yourself having sex with a male that isn't a prostitute and send it to every gay person on the site. I ask this of you because this will prove that you choose. If you don't look like you're enjoying it the video is invalid; have fun proving your point.
For everyone who is disgusted by this post, good for you. I'm disgusted myself. I post this knowing that he cannot choose to do this no matter how hard he tries, unless he's paid a lot, but in that case he's a man-whore.
