Have you ever had a BJ (or any oral) that felt better than actual intercourse?
Unsurprising: I really love my BJ's.
Aside from the physical pleasure aspect, they just do something great to my ego. I feel more wanted than I do with "mere intercourse" (hey, any woman can just bend over, but a woman who goes to town on you with her mouth... that person WANTS you!), it feels like a "very deep form of affection" to me, and if I get a good one and she swallows I am just walking on air for days and will do any nasty chore that needs to get done.
