Honestly, I love the foreplay. The penetrative sex itself is obviously great, but getting each other worked up is way more fun in my book.

Eating pussy

Bonus if she squirts

Cuddling in post-coital bliss. Just holding one another close, smelling her hair. Mmmm

Intimacy

My wife making ahegao face is a close 2nd

initial insertion

I guess some would call it foreplay, but I just think of it as the majority of sex. Whether we're working through the kama sutra or some tantra, doing some roleplay, bondage and flogging, or whether my partner is sitting on my face and telling me what a shameful dirty fucker I am and that if I want to breath I better get my tongue deeper inside them; orgasm and intercourse is great but the real sex is the nasty fun stuff we do to each other before, after, and ideally during. My hottest dream scenario would be to participate in a highly ritualistic occult orgy, with all the costumes and esoteric purification practices and everything. Bonus if I'm not the main focus, but am just a ritual tool for my partners to obtain some sort of erotic spiritual goal.

Gay guy here, honestly just bringing my boyfriend to the point of no return; I don’t need to nut myself because being able to help someone do it makes me feel so good.
