Hi In the last couple of years I experienced a weird sensation in my right thigh after sex. It last about 1-2 days and I can feel it only if I stand up or walk slowly. Any real activity and it dissapears. But standing feels like I loose control of the leg, like the nerves are somehow affected (it is not quite numbness, but hard to explain). And after few minutes the sensation gave way to a feeling of pain that grows and becomes unbearable. Sit down and dissapears.
Dear friend, I have understood your problem, you don't need to worry at all, it's common for all couples, see this is like how you feel just after doing intense exercise and feeling of fatigue then after, same as that sex act is also intense energy consuming act where you do continue vigorous action of your thigh muscles which are not accustomed to strain, you just after an act you will feel soreness or plumpness see what you can do is first increase your foreplay and after play. Take rest as soon as you finished your sex, be with partner for 10\u00a0min. Then slowly sit up. don't do sex vigorously. Do everyday strengthening and stretching exercises, yoga and Panama and mediation practice which will minimize your problem. I hope you have understood and satisfied with these answers.
