Also consider that many are of the mindset that you can go through different sexual identities in different phases of your life. You may go through several years feeling asexual, and then a period where you do desire contact, and then go back to being asexual again. Not everyone agrees with this, some say you either are an asexual person or you are not, but many do. It is certainly something that I can relate to. I too have struggled with feeling like I am the only person who doesn't desire sex in a completely sex-obsessed world. Everywhere you look, everything seems to be based on the human desire for sex, and I find it foreign and often annoying. It's just not something that would ever enter my mind. I just added a documentary called (A)Sexual to my Netflix queue, I think it should be interesting.
This is interesting that you say these things. I've also often found myself feeling like this. I never had a girlfriend, so everybody for a while assumed I was gay. Well, no, because I'm not attracted to men either!
It honestly hasn't been until this last year that I actually started wanting to have sexual relationships. I was perfectly content to be alone, but now I want to start dating. I want a partner. It's odd; is this how most people have been feeling all their lives? Did I just hit puberty at age 28?
