What excuse do you guys make to come up again after heading down?
I've only once had the experience of a disgusting smelly vagina, unfortunately I was young and naive at the time. I smelt something as soon as I picked her up (it was a rare outcall to a hotel), tried to encourage her to share a shower with me, didn't happen - I'd seen her before we no hassle. Only when I get her nickers off did I realise the source of the stench was betwixt her thighs when I tried to go down on her. Instant erection killer, tried again to get her in the shower, again she refused, so I faked a phone call and said I had to go, she kept the cash.
These days I think how I dealt with it would depend on how well the punt was going up to that point, I'd try to get them in the shower, if that failed I'd tell her discreetly that perhaps she should give things a little wash. She'd not appreciate it if I had a smelly cock and as the paying customer I expect her to be clean. Doubt I'd be seeing her again.
