About the pain hard by my groin, after a sexual intercourse, is it overexertion or what?
what is the best remedy to avoid its recurrence?
Answer: You are probably straining a muscle in your groin.Depends a bit how long you have be getting the pain and if it solely appears after intercourse.Sometimes you can get an twinge relating to the testicles. Try giving the nookie a rest for a while(if your partner lets you)and see if things raise.If not see your doctor. it might be a hernia.
Dont do it!!
It happen sometimes when you have to work unyielding in an intercourse...try different positions...try avoiding hurryness..it happen with me when I used to masturbate near a firm fist...it doesnt happen presently while intercourses..
It could be referred pain from your prostate gland. This would indicate that you own some prostatitis going on and you need to consult a urologist if it continues.
Good Luck
