Is it solely arousal? Or finding someone's nudity aesthetically appealing? Or wanting to be close to someone and date them? If I don't really ever think about sex and don't masturbate, how do I figure out which gender(s) I'm attracted to?
Sexual attraction to me is who I want to have sex with. I get aroused quite easily with guys that I'm attracted to, but with women it's rare. If sex isn't part of your interest at the moment, feelings can help you too. I love being close with my boyfriend, and he's always on my mind. Seeing him gets me an erection everytime (not always a good thing lol). The statement "I have a boyfriend" feels right for me, whereas girlfriend does not.
gbxx33, give time to time... Eventually you will figure it out! I relate to Jax12. It is who you want to have sex with.
The feeling you get when you look at a really pretty boy and you JIZZ IN MY PANTS No just kidding, I have much more self-control than that. But yeah, that feeling.
