People who enjoy pain during sex are called "masochists," after Leopold von Sacher-Masoch, who wrote several novels about this. (People who enjoy inflicting pain on others are called "Sadists.") There are at least two theories about why some people enjoy pain during sex. Some people think that it allows the masochist to eliminate guilt by being punished while having sex. Some people think that masochists "get high" from the endorphins the body releases when it's in pain.

"to dull your pain" Could mean to distract you from your pain or take medicine such as pain killers to make the pain less noticible to you.
