dress rehearsal 

dry humping, going through the motions of sex without all that pesky penetration. there must be at least one type of fabric separating the required genitals at all times. no contact!

guy: you get some last night?
dude: naw, only a dress rehearsal. now i have blue balls.

NASA Dress Rehearsal

When sleeping next to your partner and you line up your butthole directly with a partner’s hole and fart. Their reaction let’s you know if the rehearsal was a success and you’re ready to move on to space docking.

I woke up my wife by lining up my butthole to her butthole to perform a NASA Dress Rehearsal before the space docking later in the month. She screamed that she felt the fart deep in her butt. I knew then, my years of preparation made me ready for the Space Dock. T-minus 20 days…

dress rehersal 

The act of self pleasurement whilst using a condom, often to see if is the right fit and/or suitable.
similar to a Posh Wank, but with intent.

"hey babe, dont worry... These rubbers wont break, I had a dress rehersal with them yesterday."
