I've always found lables to be silly...but, in this matter, I've decided to choose one.
'asexual'.
It explains why, in context of relationships and people, the actual physical idea of sex turns me off. I don't mind the hugging or the cuddling on the sofa to watch movies, and a good shoulder massage always makes me melt, but the moment someone moves in to give me a kiss or even go further is th moment I back away and shut down.
I think a small place in the back of my mind is revolted by the idea.
That said, I don't mind if other's have sex. Heck, I don't mind getting involved romantically with people (male or female), as long as they understand that I'm in it for the smiles and the laughs and the quiet moments of watching movies or looking at the stars. Those moments are peaceful--that's all I want, really.
If the person doesn't understand that, its usually best for me to break it off and focus on my academic pursuits. Who needs a pushy lover, anyway?
Because I'm considered 'strange' by the norm, I fully support other people that are 'strange' by the norm. Some of the nicest people that I've met have been gay (my uncles, for example), and it really is unfortunate that people are stigmatized for what has essentially been a part of humanty since the beginning of time.
