I'm asexual. I've never felt sexual attraction to anyone and don't feel the desire to have sex with anyone either which I'm fine with. However, I like big breasts, I like big bums and I also get aroused but regardless of this it doesn't change how I feel. The difference between me and someone who isn't asexual is that when a woman gives a sexual person an erection that man probably wants to have sex with her however, with an asexual they either just wait for it to go down or take care of it themselves and resume their day. A sexual man will see a sexy woman and think "I'd do her" but an asexual man wouldn't.
Do people see where I'm coming from?
