When Anal Sex Takes Place Without a Condom, the Insertor

When anal sex takes place without a condom, the insertor should urinate soon after withdrawal because

A) semen that gets blocked needs to be cleared as soon as possible.
B) tight sphincter muscles cause urine to back up in the urethra.
C) lubricants that are not fully expelled can damage the urethra.
D) spermicides can cause long-term damage to structures of the penis.
E) fecal particles in the urethra can cause infections.
