I don’t really have any weird turnoffs. Bad teeth, bad personality and excessive body hair are about it.
I second the too much makeup bit. I prefer NO makeup 99% of the time, but I admit a little bit can look nice.
Also, a good voice. I’m no singer or anything, but if her voice isn’t pleasant, I can’t take it.
Armpit titties on a man.
- Makeup
- Poor table manners
- Nothing about Opal is a turn-off.
Men who go to tanning salons are a HUGE turnoff for me. I haven’t run across it that often, but recently, a friend of mine who was about to leave for 2 weeks in the Caribbean told me he’d gone tanning before he left so he wouldn’t burn. I understand the benefits of a “base coat,” but there is something so…unmasculine for lack of a better word, about it. I think women who go tanning are somewhat ridiculous, but somehow if it’s a man, it’s even sillier to me.
The traditional, buff, built Chippendale Dancer types. Brad Pitt, Tom Cruise.
I prefer the more scholarly, thinking type. Guys who look like college professors. Think Gregory Peck, or Glenn Miller.
(As if you didn’t know!)
Huge testicles.
If only there were more of you out there.
Turn offs:
Very thin men who wear tight clothing
Tight jeans or pants on a man
Speedos or other ‘marble bag’ swim wear
Smoking/smoker’s breath
Quiet men who don’t make any noise upon ejaculation (don’t ask me, I know it’s strange, it just makes me totally disinterested in getting to that place with them again)
Bad skin, acne or acne scarring on face
white socks.
even with runing shoes and shorts.
no.
the horror is still too much.
black, navy, grey, orange, red, purple, whatever. just not WHITE!
There are more of us out here than you know.
To answer the OP: I know it isn’t so weird, but someone who lacks a good sense of humor really turns me off.
In the entirely non-physical-attribute zone: bad writing. I’m not talking about legibility, here, I just mean the lack of ability to write an interesting letter. It’s one of those things that’s hard to pin down or define precisely, but you know it when you see it.
My socks are almost always black athletic socks. My mom is horrified by this. Most girls never even comment on it; the only one I can remember saying anything just said “cool.”
My turn-offs include women who are too thin.
After three kids, mine aren’t going anywhere. 
Sheri
I’m willing to accept just about any physical deformity if the guy is funny, reads BOOKS on a regular basis (not SI, thank you very much), and makes me laugh. I even like body hair and stomach pudge.
The only thing that really turns me off are men who take more time getting ready that me. I’m slightly high-maintenance; but if a dude uses more hair products than me, takes longer in the shower, or spends more time picking an outfit than I do, or fake tans, I am out the door. I just can’t live that lifestyle.
By the way, I have a cleft chin and I don’t think it’s hideously masculine. But to each his own, I guess. If you click on the www icon at the bottom of this post, maybe I’ll cause you to projectile vomit. 
There is nothing wrong with your chin Sara. I don’t find it a turn off at all.
However, eating unshelled crabs like a sandwich is another story. 
Paper thin women, You know, the kind that turn sideways and Disappear. The site of showing ribs when not bent over backwards just makes me ill.
smokers, tattoos and piercings
muscles
far rght politics;)
long hair (on guys) after a certain age, it just looks sad.
anger ( no more guys with anger problems for me)
Overly intellectual people who can’t take a joke and are self-righteous because the think they can be because the are so… well, overly intellectual.
People who mumble and expect ME to do all the work trying to understand them when all the have to do is fucking speak up!!!
Can we say arrogant?
Women who have squeaky voices who aren’t friendly to other women at all, but light up like a Christmas tree when a man walks into the room. I feel like throwing them some knee pads and saying, honey–go for it!! At least it’ll shut you up for a while!!
