I, for example, am very turned on by contrasts. So noticeable height differences, size differences (individual body parts or the whole package), skin tone, shapes, etc.
I kinda wish my wife (who’s very pale) were bi because I would love to see her have sex with a dark skinned woman that’s a similar height and weight as her, or a short, petite woman (she’s also tall for a woman).
Both me and my husband are basically, eyes face, and for me bum, for him, boobs.
Nothing else for me I think, I like deep voices, but more so, I find high pitched and scratchy voices a turn off.
But then him, being outwitted. He is stupidly smart, he has a PhD and 2 Masters, and finds someone outwitting him or outsmarting him actually a turn on. It’s weird. The odd times I do it, prove him wrong, he almost instantly jumps my bones, he can’t control himself.
