I am fraysexual and this is labelled as an orientation somewhere on the asexual spectrum.
For those who don't know, in brief, fraysexuality is incompatibility between romantic and sexual attraction: the more I love a person (romantically) the less I am attracted in them sexually.

I do have a lot of sexual urge and even kinks but ONLY for unknown people. As soon as I start knowing them (as friends, or sex partners) I lose in short or sex interest into them. Either I friendzone, either I don't relate to them at all. This sounds like an a-hole move but I always warn potential partners at the beginning on a date about how I am, so I don't promise them what I can't give.
In exchange, I can maintain a platonic romantic (if I can call it so) relation for years (ideally for life). My dream would be to live together or meet often a good friend, that would be like a sister to me, having deeply feelings for her but no sex. This is very asexual.

In exchange I'd like to also have side-sex if the occasion occurs, as ONS' or FWBs with no comittment, with the agreement of my partner. And this is less asexual and looks like ethical nonmonogamy. I wouldn't mind if my partner has side-sex on her side or not (as she wishes). I'm not even SURE I'll have side sex on mine, but would like to know that the possibility exists.

So, what do you think: is this asexual or not? Aromantic is not, since I can be madly in love with an asexual partner and think only about her and feel on the 9th cloud.
