Pain in groin. 9:24 pm male, 21 years!

Pain in groin Sir, I have strong pain in groin on the left side. It's due to the masturbation. I masturbated almost daily for last 4 years and that's how the problem started. The problem is totally physical and in bones. Everything else is fine. I just feel pain when I try to contract my left leg (trying to touch my chest with knee). I can touch my chest with right knee, but cannot with left one. I feel pain. Also when I completely straighten my legs, making them perpendicular to my torso- I'm able to lift my right leg from perpendicular position. But I cannot lift my left leg. I feel pain in groin. I can't tell exactly but it feels there's some kind of disjoint in groin area. 9:24 PM Male, 21 years
