Why do some girls like to get hit while sex?

[Anonymous]

Some girls asked me to slap pussy harder and squeez boobs so hard..
They says its a big turn on..
Why?

Mixing pleasure with pain. I don't know why they enjoy it, but that's what it does. It may have to do with how the first few times they have sex are like that.

Because the pain and pleasure affect the same part of the brain
