Very aggressive, I take charge.
Sorry Dolfette that deserved a longer answer. I like to have a good time sexually, I know if I take charge that's exactly what I'm going to get, I've never been shy about asking for exactly what I want and every guy I've had loved that I was so upfront about my needs - I see ladies complaining about selfish guys but in my experience men are really eager to please, so knowing that they're giving me exactly what I want really gets them off. I have friends who complain about their blokes putting on a pretty poor performance in the sack yet they won't even take five minutes to explain what and how they like it.
There are alway two people in bed (if not more) if you're having a crappy time it isn't one of you that's bad, its both of you together and you each have to put your tuppence worth in to make it work. I make sure it works because I tell him what I want, read his bodily responses, but also use what I know of him as a person to judge what he might be craving for but feels a little freaked out in asking, and ask him what he wants.
