I don't know if you have ever discussed fanatsies with your SO before . . .
But I have had past GF's bring it up and they'll ask what my fantasies are and I have to wrack my brains.
I don't think I, and most men, really have fantasies per se . . . I mean we think about sex .. . a lot . . but not in terms of elaborate scenarios like women seem to.
Women have descriptions of scenes, people, props, like little playlets.
So finally I saw Bill Maher comment on this. He said our fantassies just don't mix.
Your fantasies bore us. Our fantasies disgust you.
Because you rarely see a female fantasy playlet where the Handsome PRince runs across a field of green with floating butterflies to the tune of some romantic song and the ejaculates all over her breasts and face.
What can I say, just a difference in the genders
