I believe in foreplay with women, which may suck for women that only want a slam, bam, thank you, ma'am guys.
Why?
I need foreplay with my partner. I am high libido also so one can never assume.
I do like my nipples played with and my neck nuzzled and soft touches. But hey we are all human no?
As for your nipples, well a man always must have a challenge, but the key is one can't focus on them and you so dearly need kept on edge where all body parts are sensitive.
