Slight turn-off:

-Body Odor
-Dirty-looking clothes
-Strong Cologne
-City-life people (sorry, I don't like party-people. Call me boring)
-Too many tattoos
-Greasy/Oily hair
-People that drink (only a slight turn-off, due to an odd fantasy >_>)
-Chest Hair
-Facial Hair (It's good on some guys but, for me, not many of them)

Major turn-off:

-Belittling me
-Smoking
-Druggies
-Bad Breath(which goes hand-in-hand with smoking, really)
-Ass hair (I take the time and effort to shave it, others can too >_>. It is, literally, a pain in the ass to shave.)
-Guys that fart near me or others
-Trying to be something they aren't
-Guys that want to talk about religion or politics
-Dirty or unhealthy-looking hands


It's easier to think of turn-offs than turn-ons. XD I'll stop with what I've written so far. :p
