I've mentioned this in another post I made just now but I thought I'd open a new thread for the topic because I realized this really bothers me.

I'm 21 and I've never actually been sexually attracted to anyone. I'm in my second ever relationship right now and I'm not even attracted to my boyfriend. Of course I've seen guys around that I thought were handsome or even sexy but I've never ever experienced a moment of actually feeling any kind of chemistry or physical attraction. The fact that I'm a virgin probably won't come a shock at this point.
Many times in my life I have already considered if I was possibly a lesbian but I'm even less attracted to girls. I think asexuality also isn't a possibility because I do get sexual urges, I do masturbate and watch porn and all that - I just haven't felt that way towards any real person.

Could it be that I'm just too much in my head space and overthink things too much to allow these kinds of feelings into my head when I'm around people? I never fully relax when I'm in the company of others due to my social anxiety, could that be the issue? Has anyone got any idea on how I could possibly start working on this? I've only been in this relationship for less than a week and I know he won't pressure me into sex but I do want to have sex at some point - I just don't know if I can.
