Hi Salvador,
I'm sorry to hear you are so down about all this. Lots of hugs!
I consider myself asexual too, and at times I feel like it has 'destroyed my life'. I really want to find a (male) partner for myself (female), but it feels like all the men I meet want sex very badly . . . I can assure you, that for some very woman you will be exactly what she wants!
You talk about a cure . . . I think you know there isn't one. I also know that's a really annoying response, because I've wanted to "cure" other problems and I really hated it when people said that to me. Sometimes it's possible to cope with a problem so well, though, that you feel cured.
There are lots of ways to "have sex" outside of coitus - even though my culture (and I presume yours) tell us that is the pinnacle of intimacy and relationships. Maybe one day, you'll find a method of sexual relationships that work the best for you, if you decide that's what you want.
I don't know but I wish you all the best.
