Railing

The head of your penis needs to tap her vulva. Some believe the shaft needs to hit, but once just the head happens, railing has occurred.

A doctor might say you've been "Balls Deep."

Dude, after downing three Flora Doras, I blacked out. I woke up hours later, railing that hot girl from the Boat Launch!
