As a Cosmo girl, you always keep things creative in the sack. But if you still have a few racy curiosities floating around inside your mischievous little mind, you're not alone. Here's how to take your sex life to the next level.

Q My guy wants me to tie him up. Exactly what do I do once he's bound to the bed?

A Savor this opportunity to show him what sexy means to you. "Tease him all over so he won't ever know where the next touch is coming from," says Barbara Keesling, PhD, author of Men in Bed. Since he can't escalate firings to intercourse, he'll have no choler but to focus fully on every sensation, which ups the overall intensity.

Kiss down his body, spoiling sensitive areas like his nipples, ears, and neck with your mouth. Lick from his ankles to his inner thighs. Breathe against his soft (or hard) spots. And look into his eyes to remind him that you're in charge ... and loving every second.

Q My boyfriend likes it when I touch his butt during sex. Should I go further?.

A Exploring this nether region can be exciting for both of you. Next time, grab his butt cheeks, and give them an extrafirm squeeze. If he seems turned on, he probably wants you to keep going.
