My wife and I have been together for nearly 13 years now. Luckily, like fine wine, lovemaking has only gotten better through the years, and even better since the children. We still have a very healthy sexual relationship, often 4-6 times per week, and from foreplay to climax, a ‘session’ can last anywhere from 1-2 hours.We have never had any problems experiencing orgasms together, but over the last two years her orgasms have changed and it raises not only my arousal, but concern as well. She will often experience powerful orgasms, often so powerful she will, as she says, ‘get fuzzy’ and pass out. This will happen sometimes 2-3 times during a session, intercourse or oral sex, and last from 1-5 minutes.At first I thought she was tired, but I had to carry her once and she was completly limp in my arms and I woke her with an ammonia inhalant. She insists that it just feels so go she cannot help it. She has seen her regular doctors for checkups religiously with no problems.My concern is as follows. While I am thilled that I can pleasure her to such limits, I do not want to put her at risk for my pleasure. Is this something that is common among women who experience strong orgasms.
