The only thing I always really crave is giving oralsex, even when not in the mood for intercourse, I can't seem to turn it down. It's just easier and always give me some kind of pleasure. I also seem to crave it much more than receiving. It's just easier, to receive you need to be in the mood for it, and it takes more out of you or make you feel more vulnerable. I guess this is an area many where many would disagree. But personally I feel giving is both more of a turn on and makes you feel closer to someone, gives you more of a rush, and I just get more out of giving in general.
