When it comes to sex, there's a lifelong learning curve that doesn't stop just because you tied the knot. Yet, "many people fear that asking questions about sex will lead to judgment or conflict with a partner, and no one wants to rock the boat," says Madeleine Castellanos, M.D, sex therapist and author of Wanting to Want: What Kills Your Sex Life and How to Keep It Alive. "But getting married doesn't magically make you instantly proficient at all aspects of sex with your partner." So if you've got embarrassing questions you can't spit out to your spouse, let alone a professional, it's OK, because we've got the answers you're looking for.

"Women are really careful about protecting a guy's feelings -- and this can lead to putting up with stuff they don't like instead of communicating what they would like to be different," says Castellanos. Start telling him what you really like, suggests Castellanos, with conversation-starts such as, "'I really love it when you,' or, 'I think that I could reach orgasm if you did that non-stop for awhile.' Become curious about the process and think of it as researching what feels good. This helps keep you aroused rather than turn to frustration."

2. How often should I be having sex now that I'm married?

Like many things in life, "it's not the quantity, but the quality of sex that counts," says Ava Cadell, certified love coach and author of Passion Power for Couples. "However, if he wants sex every day and you want it once a week, you should negotiate a win-win compromise that includes masturbation, foreplay, oral sex and intercourse."

3. Is it wrong for me to fantasize about things other than my husband to get excited?

"For many people, there is an underlying feeling of guilt if their sexual fantasies turn to something or someone other than their partner," says Castellanos. "But this is not only OK, it's normal." Why? Castellanos explains that "sexual fantasies are similar to dreams -- they are symbolic and have more to do with an underlying theme rather than the details of who or what is going on in the fantasy. You don't really have to read too much into it or try to analyze it -- just let it build your arousal, which you are sharing with your partner anyway."

4. How do I tell my husband about my changing libido now that I'm pregnant?

First, know you're not alone. "It's common for women's libido to either dissipate or increase during pregnancy because of hormonal changes," explains Cadell, "so let your husband know how you are feeling during the different changes of your pregnancy as he cannot read your mind. This is a great time to include sex toys for both of you to maintain passion and playfulness. It's also a great time to enhance intimacy through kissing, synchronized breathing and caressing."
