Levellius, I’m pretty new to PE also, but I think I can answer a couple of your questions. First off, yes, Jelqing can be dangerous to your penis.. If you do it incorrectly that is. From what I understand, Jelqing does put some pressure on your penis which in turn causes micro-tears. If you don’t over do yourself and have plenty of rest days, your penis will naturally heal and in fact, get bigger. I consider it similar to working out your biceps or something. You are putting strain on your muscles, and I’m fairly certain (not a 100% though) that this causes slight tears in the muscle tissue. With proper rest, your muscle heals and in fact gets bigger (go figure). Jelqing helps improve the circulation to your penis, and it may give you better, harder erections (as with many of the PE exercises on this page).
Concerning the ligaments and erection angle, some of the more experienced members can help me out with this. However, I’ve been reading some on this site and I haven’t found a single thread yet about how someones dick is pointing straight to the left do to PE.
I believe PE is safe, if you do it correctly and don’t rush yourself. This is an excellent site because it not only has people who have done the techniques and can offer advice, it has helpful information if you think you’ve injured yourself. In my opinion if this place was unsafe or didn’t produce results, it wouldn’t be here! Hope everything goes well for you
