Build Bridges
If your goal is simultaneous orgasms, use the technique most sex therapists recommend. The basic idea is to give you clitoral stimulation almost right up to the point of orgasm — and then let his thrusting trigger the final orgasmic reflex. This effectively provides a "bridge" between clitoral stimulation and intercourse (that is, he stimulates the clitoris right up to penetration, then his thrusting takes over as your prime stimulation). Some studies show that up to half of women who couldn't previously climax through penetration alone gained that ability — without "priming" first! — after using this technique regularly.

Deliberately Develop Orgasm Triggers
The more your brain travels a certain path neurologically, the more effortless it becomes. The act of smiling — actually curving your lips upward — lets your brain know you're happy, which triggers the release of serotonin, a hormone that makes you feel happy. The same applies to orgasm: The more signals of impending orgasm that your brain can recognize, the easier it will be to trigger the orgasmic response. Focus on the things you naturally do on approach to orgasm — sounds you make, how you move — then exaggerate them.
