A:
If you really need to know the answer to this, you gotta see a shrink. The mind, especially the sexual mind, is a fascinating thing. But since you have a partner, you're having sex, you're getting turned on, perhaps you shouldn't worry about why.

Lots of folks like to be humiliated sexually. Perhaps they are overconfident or overbearing in other parts of their lives. Maybe it fills some deep dark need.

If you're having a good time, don't worry about it so much. But if this nags at you and you really want to know, you're going to have to go for some intensive head shrinkage.
