Back before I met the Beloved and was looking, there were several occasions when I saw girls that I thought looked cute/interesting/worth talking to.
Then they would pull out the smokes.
That was it for me. Wouldn’t even bother trying to get to know them.
Conceit
Selfishness
Being smelly, unclean (I’m not meaning private parts, I mean in general)
As for declining to sleep with someone for money… I think I would have to decide on a per case basis. (Though I could probably say for sure my latest ex. My current GF used to be her friend and that would hurt her. Not that I want to or that it’s likely to come up, but still… I wouldn’t do that to the squeeze)
I’m 40 and American (Texan in OKC)
Bad breath will turn me off quicker than anything.
I’m 38.
My top 10 list:
I’m 35.
Perhaps the OP should have been phrased “what traits would keep you from DATING a girl as opposed to just sleeping with her” since a lot of things that may be tolerable for one night may be deal-breakers in the long run.
Turn-offs:
A lot of things that I do not mind in small quantities become intolerable if they are too prevalent.
I’m 35, if that matters.
Hard to put a finger on. I am or am not attracted to women based on a variety of factors. I suppose ugliness, physical or mental is a turn off. I would sleep with anyone who wouldn’t endanger my health for a million pounds, although I can’t guarantee that my penis will hold up its end of the bargain…
I’m 40.
Motormouths. Men don’t care about endless details, like which shop you went to, which dress you looked at, what the price was, which store has a better price, who you thought you saw walking by as you were browsing but it couldn’t be her, she was supposed to be somewhere else at that exact point and time, and you know EVERY detail…I DON’T CARE!!!
The ones who tell you how many men they slept with. OK, so you’re saying you’re a slut. I get the point. I don’t need to know every single detail. Just shut up and let me be #159 or whatever.
I don’t think I’d turn any woman down for a million bucks, just so long as I got to duct tape her mouth shut first.
Obsequious, finish-my-sentence-for-me fawning. Incivility.
Who wouldn’t I sleep with for a million pounds? Hm. Gloria Allred comes to mind, because after I slept with her, I’d have to kill her to make sure she had no opportunity to pass on her genes.
I’m 49.
By sleeping with, I’m assuming we’re talking about sex right? Cause if all I have to do is share a bed, I become a lot less picky.
But for a million pounds, I’d screw anyone. Any sex, any weight, any age (above legal).
If I’m doing it for free, well I’m not big on smokers, bad breath, or bed hogs.

I once had a short flirtation with a woman with a firm bitchy streak. After a few drinks, she started insulting some guy across the room, while I was trailing a fingertip along her jawline and under her ear. For me, that’s kinda like eating a peach with bits of glass in it. I got loose from her, even though she made a pass at me every time she saw me for the next six months. I called her the Demon Barber, and my pals would kid me about her whenever she showed up.

I find makeup and gold jewellery to be incredible turn offs. I have never seen them look good on anybody.
I am 28.
In general? Quite a lot. I have relatively little interest in sex in the first place, so I can afford to be quite picky. 
So the following are a small set of the things that would turn me off:
Not liking the person. It seems fairly obvious, but I wouldn’t have sex with anyone who I didn’t already like as a person. Whether or not I like a person is too complicated a thing to list, so I’ll just lump all the personality things in here.
Random one night stands. They hold absolutely no interest for me.
Poor personal hygiene. I’m not talking about unshaved legs, etc. Stubble might bother me a bit, but long hair wouldn’t (although I might be a little put off by really bushy armpit hair), but no BO, bad breath, etc.
Smoking. Total deal breaker. Cigarette smoke makes me gag (not literally). I can handle it in a friend, I just try to avoid close physical proximity in this case.
Drunkenness. I wouldn’t mind someone being slightly drunk, but anyone who’s really plastered isn’t someone I want to be around at that time, sex or no. I have no real problem with people who occasionally get really drunk, but I’d prefer not to be there when they do.
S&M / Bondage / etc. Complete and total turnoff. I have no interested in being on either side of such activity. Again, no objection to people who want to do this, it’s just not me.
On the other hand, for a million pounds? There aren’t many I wouldn’t sleep with assuming appropriate protection, lack of communicable diseases, etc. As long as there are no long term effects, however you look at it it’s a fairly decent hourly wage.
Oops, forgot the age. I’m late 19 (20 in less than a month).
-Not caring about their body (includes smoking, physical fitness, hygene, etc)
-bitchiness
-being judgemental
-being mean

Was her name Sweeney, by any chance?
hmm… as a 38 YO totally happy married guy here’s what theoretically would turn me off
Ignorant/lack of common sense would be a biggie
Racist would send me running immediately
evident poor personal hygiene for sure
extreme cattiness for sure, although a little every now and then I find funny
self absorbed/talks about themselves too much- um… buh-bye.
Someone who can’t keep up a decent conversation
moodiness- aaaiyeee!!!
extreme obesity
very hairy face
very bad teeth (for example, missing ones and others pointing in odd directions)
Personality and intelligence are obviously very important to me, but not significant at all in your theoretical million pound one-night stand. I’m assuming I’d be allowed to wear ear plugs if necessary?
