Sex and relationship expert, Dr. Trina Read, is ready to answer your questions.

I want to try a vaginal tightening cream, but wanted to make sure they work before buying.

The short answer is "no" they don’t work. It’s just something else in a long list of things to make women feel insecure about their sexuality.

Here’s what vaginal tightening creams do to make you believe they work. Some numb the vagina making it so you don’t become fully aroused. That means you’re less lubricated causing more friction which can make it feel tighter, but also more uncomfortable.

Other creams contain aluminum, the same active ingredient that’s in your antiperspirant. These creams function by limiting vaginal lubrication. As well, they can cause an allergic reaction producing a swollen and dry vagina which makes it feel tighter.

The other ingredients in vaginal creams are relatively harmless. Even still, your vagina is a delicate ecosystem and when you introduce foreign products they may mess with that balance and cause infections.

Great Sex Tip: The vagina is a muscular canal. In order to "make it tighter" you must exercise just like any other muscle in the body. To do this: 1. have sex often; and 2. do your Kegel exercises regularly.

Is there any way to help me orgasm better?

Variety really is the spice of life for your sexual pleasure and ability to orgasm.

Research shows for women (and men) ages 18 to 59, their orgasm experiences were linked with sexual variety. Meaning, those people who weren’t afraid to try new ideas, tips and techniques were far more sexually satisfied.

This makes a lot of sense. When we walk into the bedroom and do the same old, same old, it’s like our brain (and bodies) go on auto pilot. When you try something new, there is the thrill of "what do we do next?" with your brain, releasing dopamine and giving you that like-you’re-in-a-new-relationship sex rush.

The goal is to "play" together rather than to have an orgasm. It’s about learning what feels good for you and your partner.

Initiate and try a tip or position you read about or heard about from a friend.

If the new idea isn’t working don’t fret. Simply laugh it off and try something new. Ask your partner what they like. Tell them something you want to try.

By bringing new ideas into the bedroom you have nothing to lose and everything to gain.

Great Sex Tip: No two orgasms are ever the same, so enjoy the uniqueness of each of your orgasms.
