I wish I had your daring, I have been with plenty of women coming from a bar or club and there have been plenty of times when the vagina has just been absolutely rank, I'm guessing from asscrack sweat seeping down onto the canal entrance. What I've done in the past is simple to administer a finger test. If it failed, I ejected / made up an excuse and got the hell out of there.
If only I were able to force them to shower and triple wash the crack, I could have saved a substantial margin of my failed same night lay attempts.
THIS.
Thing is I never played tough guy. Never played cool guy. Never played player. Never played type slick. Just insisted on being myself and it so happens I'm ACTUALLY an interesting person to most ppl, and especially women. And I know how to fuck to put most of my competition to shame.
Fact is, ppl stay in safe zones. We don't say what needs to be said on a number of fronts. I tend to say what I feel needs to be said. I'm respectful in how I deliver it, but I'm usually uncompromising. And there is a sweetness and a trust that a woman builds up with you when she has to go the extra mile. It builds a trust.
I'd bet all of those girls who you kicked out wanted cock, obv. And many of them would have wondered what made you refuse, especially if they knew how to spot a slick smell test. If you bathed them I'd expect the majority of them would be relieved (especially if your tub is clean, lol). Most women prefer to present well than to present as a stink pussy.
I should also add I was never really into clubbing so very few of these encounters came from picking up chicks at clubs. I made it a practice to approach women on the street as a regular part of life. School of hard knocks - no alcohol, no sexy setting, no music, none of that. Walk up to a lady and tell her hello and compliment something about her. When she smiles, a simple "oooh, and a nice smile to boot" got me 50% to getting her number. If she had a brain I'd discuss real life with her, if not, I'd crack jokes and make bold, sexual offers in an irreverant way.
Women had very strong responses and my dating life was pretty much me seducing women by phone and text and explicitly inviting them over to fuck. There was a long stretch of time where I barely ever took a woman out anywhere. They'd say I was "different", "refreshing", "honest" (I got that a lot, lol!), etc.. And I'd tell them flat out that I wanted them to come over because I found them sexy and I would graphically explain things I'd do to them when they came. They all knew they were coming over to fuck and they all looked forward to it.
If nothing else, I'm an explicitly honest person, and humans appreciate that in general. Women appreciate it sexually. When a young man asks about talking to women I always have the same first point of advice: "be bold, be honest, be imaginative, and be EXPLICIT" - leave little up to chance and feed a lot to imagination. Tell them you find them sexy and tell them how you'll fuck them. Learn how to paint a seductive picture. And learn how to fuck, lol! Create referrals and repeat business!
It's just basic sales at the end of the day. Same shit I do at work.
EDIT: and have an active and flexible sense of humour. When humans don't know what else to do or say, they love to laugh.
