Combination of things already mentioned. I'll say some of them again for reiterative emphasis.
Piss poor attitude. I put this first because this sets the tone (or fucks it up) for the whole evening. Acting like you're doing me a favor by taking my $ (and by taking I mean conning me out of it) will not only get you NOT seen again, but it will lead to a bad review AND you possibly getting cussed out. I probably won't do the last one...unless her attitude is just WAAAY out there.
Acting like you're scared/too disgusted to touch a dick, that's close kin to attitude. This is the wrong business for that. It'd be one thing if I had a chewed up, scaly, reptilian looking meat with sores or some shit all over it. Not only am I usually well groomed down below, but I happen to think my dick's not all that bad looking, as far as dicks go in the looks dept (whatever that means
).
Cbj is not a dealbreaker, but don't try to put a rubber on a limp noodle. Hell, if you want to be technical, the INSTRUCTIONS say to put it on an ERECT penis, so you're fucking up already. It's like putting a sock on a stick of melted butter...as in EXTREMELY DIFFICULT to do. Mutual touching, sucking on the titties, etc, those things tend to trigger blood flow to the wood. I know every girl's not a kisser. If you're not, at least allow some contact to happen before you try to cover us up.
No MSOG. Not necessarily a dealbreaker, but MSOG friendly providers get bumped to the front of the line. I'll be hesitant to see a nonMSOG'er and will definitely weigh other options, even though the older we guys get, the least likely a second pop wil happen. Still we'd like to believe it COULD happen.
Odor. Nothing's worse than a smelly kitty/ass. NOTHING. This should be #1, actually.
Fake pics/NCNS patterns/obvious or overbearing management.
