an activity in which a man inserts his erect or stiff penis into a woman's vagina (aka pussy). he then may move it in or out
i was talking with my boyfriend the other day when he suddenly backed me against the wall and began to remove his pants. i removed all my clothes and we began to have sex.

Most commonly, when a man puts his penis (also known as: dick, hard-on, wood, stickle, sperm injector, weiner, fuckly stick, floppaloppagiss) in a vagina (also known as: va-JJ, donut hole, ovary exit, baby gun, humplestiltzskin). Recently, some gay men have put their penises/dicks/hard-ons/wood/ stickles/sperm injectors/weiners/fuckly sticks/floppaloppagisses in other gay men's butts (also known as: asses, poop holes, brownie makers). Lesbians (gay women) have sex, too, but it is unknown how. The best guess by scientists is that they stick their big toes in to the others vagina/va-JJ/donut hole/ovary exit/baby gun/humplestiltzskin.
Man: Want to have sex?
Woman: Sure dear.
Man: Let me stick my penis/dick/hard-on/wood/ stickle/sperm injector/weiner/fuckly stick/floppaloppagiss in your vagina/va-JJ/donut hole/ovary exit/baby gun/humplestiltzskin.
Woman: Ugh, ugh, ugh, UGH!

Man 1: Wanna have shex?
Man 2: Sure hotstuff.
Man 1: Let me stick my penis/dick/hard-on/wood/stickle/sperm injector/weiner/fuckly stick/floppaloppagiss in your butt/ass/poop hole/brownie maker.
Man 2: Eeh, eeh, eeh, EEH!

Woman 1: Want to haf the sex making?
Woman 2: Sure carpenter.
Woman 1: Let me stick my big toe in your vagina/va-JJ/donut hole/ovary exit/baby gun/humplestiltzskin.
Woman 2: Ruff, ruff, ruff, RUFF!

The starter of all problems. Consequences: unplanned pregnancy, dropouts, disease, the end of "fun", second guessing of relationships, pornstars, whorism and sluttiness, a baby, Juno, etc. Etc. There's a 5% chance of sex turning out for the better.
Sex caused my start to parenthood.

Half nausious pain, half complete and utter, breath taking pleasure. When a man pounds the shit outta a girl until she moans like a slut.
"Dude, last night she gave me dome and so i pounded her pussy as we had sex.."
