A question for the ladies: in general, how long does it take a woman to develop the ability to orgasm with a partner, after they first start having sex?
I asked my wife. She said that her first real sex partner was never able to bring her to orgasm after 3 or 4 tries. The second partner only had two chances and failed. Her third partner knew what he was doing and brought her to a great orgasm the first time they had sex. In my case with her, it took 10 or more times for me to figure it out and get her to orgasm.
