I have chosen it, because it doesn’t have any smell or nasty taste, it’s neutral to skin and (the main reason) is a good lube. Maybe some vitamin E content can be beneficial, I don’t know.
Second question is quite hard to answer. Maybe these could help:
-couple of months is enough to try fulcrum stretches
- PI’s are good, but there aren’t any gains. This could be undertraining. You could do too short workout. Try to experiment, if longer/harder workout can give PI’s and obviously gains.
- I am not a veteran of JAI’s, but in theory, these are something like dynamic stretches. For me, better are long hold static stretches- best example is fulcrum stretch.
- I recommend fulcrums in Mem’s idea, because:
they are quite risk-free,
gave me most of my length and some girth gains (I suppose I’m hard gainer),
allow you to be warmed, relaxed and stretched for long periods.
Keep in mind, there aren’t any “holy rules that you must to do”. But I sincerely recommend two manual exercises- dry jelqs and fulcrum stretches. Simple, not so risky and effective.
Cheers.
