You know what, I am very blessed too. And I don't desire sex. I am the same way I think about men and masturbate but I have no desire for actual sex.
I was just in a sexless relationship and he broke up with me because there was no passion and no spark. That is understandable, but at this point in my life I think having a good friend is more important than a relationship so that's where I'm at right now.
I think its just not for some people. Yeah you may be missing out on something, people tell me that ALL the time, how I'm missing out on the "greatest thing". Well you know what, I'm pretty content in my life and I am very lucky with the love from my parents and my sister. Sex isn't the be all end all in my opinion, its just whatever makes you happy
Good thread and subject
