How freaky you lookin to get? Go to a sex shop and see what they have that peeks your interest.
Being tied up is nice, but I caution it should only be doen with two people who trust each other implicitly.
You could get "body chocolate", which is not incredibly tasty but hey- you're not supposed to have a meal, you're supposed to have an intimate encounter with your SO.
Of course... there's always anal.
(if you don't already, that is.)
**Advocates anal as much as possible** It's very good, you MUST try it. It doesn't hurt if it's done right. You have to take time with it before you plug a penis in there. Be safe, all!
