Carrying on from the other thread you spoke in, what makes you think you might be asexual?

Whatever the case, you could always check out information on asexuality on the Asexual Visibility and Education Network (I'd better not mention them again for a while, feel like I'm starting to spam lol) and there is a community there too, so if you really do feel you are asexual after finding out about everything, or need people to talk to while you think through the process, you might find friends at the very least on that site. There are hundreds of asexuals active in a memberbase of tens of thousands. Some of those are even in relationships and even got married from meeting on AVEN. Asexuality does not mean you have to be alone.

As I said on the other thread, and Googley has made connection to above, feeling like you aren't good enough, or will never be successful, or no one will ever like you, does not make a person asexual. They can be feelings created by a person being asexual though, since you can feel that you can never have a mutually fulfilling relationship if the other person desires sexual acts and you don't, or if society batters you down so much that you decide to shy away, but in themselves it may just mean that you need to work on your self-esteem and get some strength back.

Either way, I hope you feel better about yourself soon.
