I'm 26 and I've been wondering if I am asexual as well. I joined an asexual dating site and met some people there. I learned a lot about asexuality on AVEN. Just google AVEN.
It was very refreshing to meet guys on a dating site who were not interested in sex at all. We are only 1% of the population, but if we work together to educate others we may have as much visibility as the gay community.
This is a valid sexual orientation and I'm proud to be asexual. GO ASEXUAL PRIDE!
