In a perfect world, a Playmate would have enough room on her Data Sheet to list all of her turn-ons. Instead, she has to leave it at a few sexy suggestions -- and leave every red-blooded man on the planet wanting more. We feel your pain, fellas, so Playboy magazine has asked a few open-minded Playmates to kiss and tell. The result is Centerfolds on Sex, our monthly romp between the sheets with the world's most beautiful women.

Current Playmate:
Julie Cialini, Playmate of the Year 1995
This gracious New Yorker doesn't believe in rules during foreplay.

I LIKE TO FIND MEN'S SECRET PLACES
Some men have really sensitive nipples. Very sensitive. It's amazing how they get erect when I start playing with their nipples, slightly biting them, licking and biting them in just the right way. I also like to suck on them. Men appreciate that. I like to explore all of a man's body. When I'm engaging in foreplay, there shouldn't be any rules. Absolutely no rules in sex play. Otherwise it's not fun.

DON'T UNDERESTIMATE A SMALL PENIS
I've had penises that were small and some that were very big. As long as they get the job done, that's what's important. Size doesn't really matter. It's definitely true that a man who is smaller tends to take care of a woman better. Because he knows he's not a certain size, he tries to please the woman more. My ex wore a size 14 shoe, so he was very big. It's weird when you've had someone so big and then go to someone who is small; you're like, Oh, my God. But the most important thing is just having a good time. Someone who loves you and adores you and would do anything for you, who has a good job, who's secure, who has something going on -- that's what you should be looking for.

THE PROBLEM WITH 69
I like oral sex a lot. I can do it for a long time. Yeah, a long time. Actually, I like doing 69 for fun. But I prefer for a guy to do me, and then I do him. I've never found a comfortable position when doing 69, because I'm tall and a man has to fit the length of my body perfectly or it doesn't work.
