Male nipples are actually more pleasurable than the female nipples.

As in male bodies derive more pleasure from the nipples being stimulated? That's right.

Women don't know, so they don't do it. And men, they're hardly bothered because they're bothered more about procreation.

I think sex is very different as an activity.

I think for a lot of men, it's just about the final result.

There are guys who actually care about the partner's orgasm also, and who prioritize that in sex.

Actual fundamental key difference is for men, sex is about the orgasms partners.

But for women, it's about the whole process.
