There are no stupid questions when it comes to sex, and with Valentine's Day around the corner, we figured having a clinical sexologist answer your most perplexing questions about all things conjugal would be the best gift we could give you.

We've got our expert -- Ian Kerner, PhD, author of "She Comes First: The Thinking Man's Guide to Pleasuring a Woman" -- and now we need to know what you want to know.

Role play? Oral sex? How to talk dirty? More orgasms, please?

Ask away in the comments. Then we'll pick our favorites and have Kerner answer them for you, so be sure to check back next week.

Don't be shy -- you can create an anonymous commenting handle so nobody will know your business. Besides, there's no such thing as too embarrassing around these parts.
