Hello all. This is my first post and I've been a long time reader, just mainly taking in all of the great help many of you have given others as well as enlightening me on many topics that I've questioned myself and even created new ones. So, a long overdue 'thank you' for all of your help! :smile: Now, on to my question. Certainly anyone is welcome to respond, but I just felt that the ladies might be the best source of help. My current girlfriend of a year does something that I've never witnessed before and I'm wondering if someone can shed some light on it as to why it happens or what exactly is happening. Here goes: Her legs twitch (shake, if you will) uncontrollably for a good 10-20 minutes during which time she can't even attempt to stand or walk. Predominantly, it begins around 5 -10 minutes after we're done having sex. On a few occasions, it begins as soon as I withdraw, and even rarer still, it will happen during. I know that some are going to say that it's from her having an orgasm, but the timing of this is throwing me off. Her orgasms have happened long before the shaking begins. Not sure if it's relevant or not, but she is extremely orgasmic and has quite a few during sex, so perhaps that plays a part? I don't know. I'm certainly not complaining in the least...it's just that any shaking that previous partners have displayed has been preceeded immediately by her orgasm. This, for the most part, is a 5-10 minute delayed reaction. Any help?
