Most of mine have been covered. I am pretty much a whore though, so many of these turn off could not even register as a factor for me. You want kids? Don't want kids? Have high ambition? Just want to get by and get high? Non of this really matters one fuck to me as I am generally just there for an hour or two of pleasure then it's dont call me again unless it's because you are unbearably horny.
Still I would like to add my support to what cloudy said:
I'm a straight male....
-Stuck on traditional gender roles (I CD/have some gender fluidity, and want to incorporate it into the relationship)
This really frustrates me. When people have ideas like "the guy is supposed to do X and the girl then should do X" that they have never really questioned or thought about. Nothing is less sexy to me than acting in a scripted way like this. Maybe not even bad smell. Obviously the issue is a bit different in gay relationships, but I'v still had experiences with guys who had an attitude like "I am the girl in this relationship so you should treat me like it." No, we are both just people with a random selection of capabilities, strengths, and weaknesses, and what role each member of the relationship plays should be based on this, not their gender, or assumed gender.
Another thing I find to be a total turn off is very white-bread white people who have really only ever socialized extensively with other white people and it is apparent in the way the talk. This by no means I only like white guys who pretend to be gangsta or some shit, but a total lack of worldliness is a huge turn off.
Oh and dicks that dont have some shape to them are ugly. Like ones that are just generic skin cylinders. Also I dont get that turned on if the guy isnt over about 7" at least.
Moral hang ups are tiring too
