WOW i love this thread!
and yes it actually shows common experience, and all around the world.. and having had past experiences I think i can comment from unique experience..
All comes down to the primitive...
As a guy, as all men, I did enjoy a woman taking the cum in their mouth, either direct or by licking the cocktail of juices after (via fingers etc).... it is a primitive thing, the woman "wanting" their cum... taking it .. men give it .. women want it and take it, either internally or orally... so men feel good when a woman wants the guys juice. men are not built to accept the stuff....
So with that in mind, and a little homophobia mixed in, they (and i back then) just don't naturally want cum in their mouth.... women are the takers.... seeing the act of the woman enjoying the guys cum in her mouth is arousing for a guy..
So was weird for me to have to accept that I would have to perform the act i enjoyed women doing, as a woman, for a guy!! I had always told myself NEVER NEVER NEVER.. never thought i would find a cock in MY mouth.. let alone his cum... mixed with my juice! but does sort of naturally follow, i gues part of being submissive to the man...
and not as bad as I feared........
but men will always freak with the thought, or if confronted with a woman whose mouth has cocktail taste on her lips....
you can fool them, and just go for it.. you can have handled their cock, (with their pre cum juice leaking) and fingered yourself,,, then when they are not fully watching place the obvious mixture (cocktail) in your mouth, and then go for passionate with tongues kissing...
and obviously with two women... WOW, best cocktail possible.... (a science but here! yes i taste like reg female! lol, as i have same bacteria as all women, which creates the "taste"..)
probably enough for you all to have switched off... you did ask!
