I'm a guy who is kinda like this. I wouldn't say i'm shy, but i'm very passive. I don't ever get aggressive, and am kinda known for being kind and generous but not to a point of falling in to the #niceguy category. But in the bedroom, I like to be dominant and confident as fuck. Every girl i've slept with has said that this was a huge surprise for them and that that made it a huge turn on. I don't normally talk about my sex life on the internet, and I don't want to sound like a douche. But this is something that in my experience, both men and women seem to enjoy. And i'm embarrassingly proud of that contrast of character. It seems to hurt my chances of sleeping with a woman in the first place, but once I do, it certainly helps a lot.
