QUESTION
I have not yet had anal sex with a partner and am concerned about the condom staying on. What are methods I can use to assure it won't slip?

ANSWER
Pinching the air out of the tip, correctly unrolling the condom to make sure the ring is on the outside, rolling it down to the base, holding the ring around the base during sex, using lubrication, withdrawing while erect, removing the condom while erect are some measures to reduce condom slippage and failure.
