Difficulty in pooping for semen leakage.

Respected Doctor, Firstly huge shout out for all the support and work you're doing during this hard times. Generally I try to masterbate once/twice a week. Since last few years I've been facing a problem which sometimes causes irresistible pain. After 7-8 days of masterbation automatically pain starts to my lower abdomen(this seems to become like a weekly routine in last 3-4 years). When the pain occurs it seems like there's no tomorrow. The intensity of the pain is such. As due to stay fit and healthy, sometimes I try to practice no fap and retaining semen. In those times it even increases with much proximity. Im not a habitual drinker, but a habitual smoker. don't know whether this habit of mine adding more fuel on it. I tried out some methods and techniques available online but nothing worked out. Don't know what to do to make this thing happen once and for all. I would be highly obliged if I can get any solutions from your end. Regards, Soham Chatterjee
