Asexuality is not 'not having sex' it is not experiencing sexual attraction, asexual people can have libido and this can be low or high just like anyone else. You can want sex, without being sexually attracted to someone (or so I've heard lol I'm a don't-want-sex ace)
Errr, Wah? This is getting really rarified.
So, you can want sex, but not be attracted to anyone, and that isn't because you don't find anyone you've met attractive, but because you will never find anyone attractive?
and then you can be 'X romantic', so you find someone attractive, and you want to have sex, but you don't find anyone sexually attractive.
I mean, well, err, OK, but I really think you're tying yourself in knots and making life very difficult for yourself.
I mean, I have young kids, and don't have a lot of sex with dp. I've had both relationships and flings in the past (not one night stands, I do need to actually have some inkling of a person before I have sex - so that's... err. demi-sexual, hetero-romantic?) - frankly, this is all madness. Have as much or as little sex as you want. Have relationships, don't have relationships, have sex, don't have sex (take care if you do cos STD and pregnancy) - I don't really see the need to come out about it though - just live, why on earth dwell on it so much?
