The thing I say is a REAL "Deal Breaker" is girls thinking it is 100% OK not to shower before sex...
I was with a girl who refused to let me fuck her until after she had showered. Was generally kinda obsessive about hygiene. Wouldn't let me sit on the bed in clothes I'd worn outside, shoes had to taken off at the door, that sort of stuff. This was all in my own flat too!
Yet after sex (raw) and after I bust all over her back or stomach she would wipe herself clean with kitchen roll, run to the toilet to pee and go to sleep. Next morning, no shower and straight to work like that. Woman are strange creatures!
