What are the best ways to gain girth and what exercises
So my story is that I want to mainly gain girth but length is welcome too. My length sits at 6 in but my real problem is my girth which is 4.5 in which hasn’t really been a problem but would feel better if I could reach 5 inches. I’m just 18 and would like to know could it just get bigger naturally or best to start now? What are good exercises and routines. I was just thinking of doing jelqs 100 per day adding 10 a week or something. I mainly just want to try doing one exercise including stretches.
