Do's...
Arrive on time.
Ensure you are washed and clean.
Tidy up your pubes.
Always let the guy with the smallest penis go first.
Compliment her on her looks / what she is wearing.
If you feel you are going to pop to soon, pull out in good time and relax. Or if you are a repeater, fill the bag.
Before you start put one leg up on a chair, hands on hips and survey the room.
Use your erect cock to determine the spacing in a single file queue.
Play rock, paper, scissors to work out when it is your turn.
Go with an open mind & enjoy.
Dont...
Barge past other guys.
Try to engage in small talk. "Come here often?" or "How did you vote on Brexit?" is a bit off putting.
Cross the streams. (like in Ghostbusters)
Take ductape.
Pretend to be female.
Go soft. (others may laugh and point)
Swing from a chandelier.
When you cum roll over and go to sleep.
Make balloon animals out of condoms if you get bored waiting your turn.
