A BJ may not be your favorite form of having sex, which is understandable. But I give BJs that guys tell me, without exception, are the best of their entire lives. Maybe not their best SEX ever, if they prefer other things more, but their best BJ.
For myself, my best sex I ever experienced was in fact a BJ, my first gay encounter, a circumstance which perhaps contributed to the thrill. The orgasm went on and on and on... I've never had a longer one nor more intense.
A BJ is an art form, in my view. When giving one, my goal is to blow a guy's mind, not just his dick. And I love dick, and I love it in my mouth. Unless you have that attitude, I don't think you can really give good oral.
Love of dick equals a great blow job; simply going through the motions equals a wet dick and little more. Guys who can't get satisfaction from a BJ haven't met the right mouth yet.
