Hi, i have been masterbating from 3 years and it was alright but from a week ago when ever i masterbate on abdomen region a small imflammation take place which pains slight not to high and when ever i touch it it pains or it comes under any presure. If dont masterbate a day two, it automatically becomes normal or it reduces. So my question is why this happen, is some thing serious, will it cause any problem, should stop mastebate? Plz help me.
