Women can practice and learn to orgasm with a man. I have been working with women for decades counseling, coaching and training women to improve their confidence, reduce distractions, communicate their needs, and eventually empowering them to orgasm with their male partner.
I can say that women do not need drugs. If anything, drugs like alcohol, though may reduce inhibition, also reduce sensation. Also, I can say for sure that a woman's ability to perform is greatly impacted by physical exhaustion and stress. So, when a woman has a few drinks and tries to make love at the end of the day, she is often too tired and too desensitized to have a real chance at orgasm. Without practicing and already able to orgasm, women need to be in a more energetic, more focused, and less intoxicated state to be able to orgasm with a man.
The best approach is for women to make love in the day, before the stresses of the day kick in, and before physical exhaustion adds to the difficulty. Women also need a willing partner with sufficient stamina and 'size' to stimulate noticeably and for a long period of time. There is a workshop in NYC Manhattan for visitors and residences. I encourage women to learn, practice and train because it will greatly improve ability to perform with current and future partners. Even if you are woman that does not have a problem reaching orgasm with men, having a focused partner to train with and improve techniques if both fun and memorable.
