That is me as well. When my last dating attempt ended a few years back ( before I learned I was ace) I remember crying on the phone to my sister, struggling to articulate that I wasn't upset the relationship ended, but that I was always the one ending it for every relationship I'd been in, and that meant something was wrong with me.

When I finally had a word for why I never cared for these guys as more than friends, it was both frightening and an immense relief. I *was* different and so were others, and we are all okay.

1) This is precisely what sex sounds like to this ace. There is too much intimate body fluid contact to consider it unless the other person was ridiculously darn special.

2) Which is also why when homophobes and co act like straight missionary hetero sex is inherently more sanitary and therefore not unclean both physically and morally - dudes, do you even understand what sex is? Sanitary really isn't a factor.
