I have been sexualy active for many years and just recently I had a new experience. About 3-4 min. after sex my libia swells up to 2 times its normal size and there is nothing i can do to make it go away. It has only has happened twice and it will last for almost 24 hours. I have never hearsd of this before, but anyone knows the whats or whys I would love to hear from you.
