Help with increasing my freakiness

Hi, I’ve been dating this guy who told me when we first started dating that he’s a freak, he says he’s fifty shades of nasty, and he’s worse than fifty shades of grey. I’ve tried to get him to show me his freaky/nasty side, but all he says is he match freaky/nasty. Now don’t get me wrong the sex is good, but I still want to see more. I’ve told him how can I match you if you’re not showing me. So with that being said lady’s what are some freaky/nasty things you do that turns your man on?
