Harmless eccentrics, black sheep and oddballs are brownie points for me, mental illness is a turn off. It just mentally drains me of energy.
Having pretense to bourgeoisie when she knows that she just a down & dirty ****** too also, if she is actually Bourgeois. and I can't any one who'll complain about every thing dishonesty... harlotry ... She best cook . . . cause I like to do some kind of cooking too . and there taint nothing like cooking with your mate . . .
For me it's people who pretend to be something they're not, lie they make out they're posh or really well educated, but you can tell they aren't, just be yourself, people should like you for who you are, it's a bit like people who try and change you, when they met you for the first time lets say you wore jeans and a leather jacket because that's what you normally wear, then 3 months down the line she tells you she hates you dressed like that, work that one out!
Being cold to my affections. Example if we're holding hands and it feels like I'm the only one holding hands, yeah I'm gonna be turned off.
Physical and flirty cock teases. Had a gf once that would do everything to turn me on, then just go cold turkey because she simply wanted to see if I'd get turned on. Well duh! You talk dirty as hell, run your hands all over me, knee rub my cock... of course I'm going to be turned on.... until she did that. Then I was completely turned off. Narcissism. Huge turn off for me. Lying. I do not like it. Either tell the truth, or choose not to say anything at all. Ask me anything and I'll either tell the truth, or choose not to answer. But I will not lie. Fake personalities. Be who you truly are, be truthful to yourself and to me. Then a couple of the usual....bad odors, bad hygiene, etc.
You mentioned GHB, but you forgot GBH. I still remember the guy I worked with who arrived after a hot date looking as if he had survived a few rounds with Mike Tyson. He forgot to laugh when I suggested that he bought her a carving knife for her birthday.
