I’m a fairly busy guy, and still living with my parents at home so I don’t have much time to PE. I was wondering if I could get gains just by warming up, and Jelqing? Instead of doing stretches and all. My gf says she’s happy with my size, but I wouldn’t mind getting a bit more girth. Currently at a bit under 15cm long, but girth is only about 11cm. Could I just stick to a purely-Jelq routine and get some gains? Thanks.
