I disagree that it makes no sense. The idea of actually coming into contact with other guys' loads is gross and impossible to separate from the obvious gayness of that. But, like you, I've always been turned on much more by female promiscuity than chastity, possibly because it's a projection of my male envy of what I'd like to be able to do as a guy for whom getting laid has always been so much harder than it is for almost any woman. I filnd it alienating when a woman has strict criteria for being sexual and only has sex within monogamous relationships, partly because it's totally inconsistent with what I'd do if I were female, and probably more so because it's such a contradiction with my impulses as a guy. I've always been turned on more by and felt that I had much more in common with promiscuous women who do whatever they want to do sexually. I have zero desire to come into contact with direct evidence of any other dudes when I see providers, I hope they clean up before they see me, and if it's a girl who offers BBFS, I try to get her first appointment of the day, if not her first appointment when she's back after the weekend or vacation; but the idea that she fucks guys all day long is hot to me, and much more so if she also seems like a really sweet girl. Aside from the physical characteristics that turn me on, my "type" has always been super-sweet girls on the shy side who either fucked me or sucked me off on our very first date, including my wife, who is literally the single nicest human being I've ever met.
