I am an asexual panromantic. What this means is that I do not like sex, but can form hyposexual (kind of sexual, but not quite) attractions to people of any gender or anatomical configuration. I tend to prefer androgynous people, be they butch women, effeminate men, or some form of gender queer. But really, I am not picky in these regards.
At one point I would have told you I was bi, or pansexual. I have learned from experience though that I really don't like sex. At best it is merely tedious for me. I do like to cuddle and kiss, but even that becomes a bit much after a while.
I find it is very difficult to be in this position. I would like to have an intimate relationship with somebody, but without the sex. For most this is a deal breaker, and was a major factor in the termination of my last two relationships.
I would also like to add that "Trans" is not a sexual orientation. A transsexual can be attracted to men, women, both or neither, just like anyone else.
Also; if you are looking for definitions in relation to asexuality go to
AVEN. The asexual community is relatively new, but they have been rather prolific in minting new terminology to describe various orientations. Some may think this is a case of people being "special snowflakes" (and maybe for some individuals it is) but more than anything I believe that people are simply trying to describe themselves concisely and use their labels to find community. Some will balk at this new terminology, but it sprang into being because the existing language was found wanting.
