I am 25 years old virgin. I masturbate 3 to 4 times a week. I don't do any thing so I always eat and sleep and surfing the net .this is my daily routine. Slowly I increased my weight with a fat belly and increased nearly 89 kg for 5'9 height. Now my penis got thinner and smaller and from last month I observed some reduce the hardness of my dick when erect while masturbate and while doing. So what is it. And I also have constipation for 2 days sometimes so is it pelvic muscle problem or what is it and what is the solution for it and remedies.
