I am male of 24 years old. From last 6-7 years I have a vey vad habit of sleeping on my stomach and rubbing penis in bed like strokes. Another bad thing is. When I come to discharge for not getting release of sperm in my pant and bedsheets to be dirty, I use to compress my penis between my both thighs so that sperm do not comes out. I already know that this is hurting my sexual power and my sperm count. I do not want to role on my stomach because every thing is from getting on my stomach. But controlling myself for 2-3 days during half sleepiness my mood overcome of my control of moving to sleep on stomach and doing the same and stopping sperm to come out. How can I control on myself to stop this, it is ruining my sexual life, how could I control not to move on my stomach?
