Use your mouth duh. People can feel inadequate that they haven't had an orgasm, or feel as if they are not doing it right if their partner didn't have an orgasm.

Use your mouth duh. Ads are the worst, right? In honoring your partner's parts with your eyes, you begin to realize the complexities of this amazing part of the body.

I love it when clients tell me that they think their partner's genitalia is beautiful! Once you have your mouth on your partner's genitalia, just explore.
