Hi, I am a 23 year old, it's been a year since, I had sex with a girl. But i'm addicted to masturbation, I do it every day. I try to reduce it but i'm not able to. Now I feel I am loosing erection on my penis, and I have early discharge while masturbation as well. I feel my penis size has also reduced. I'm really worried, even if I watch porn I don't get any erection. And my penis size is not like before. I thought it was because of smoking, and I quit smoking as well. I don't masturbate for 2 or 3 days and then try to do it, and it's the same issue again. What do I do? Is there any medication or a natural diet? Or what do I do to increase my penis size and erection problem.
