Oooo Oooo…..Let me take this one pleeeeeeeeeeeeeeeeeeease. I know I am not a vet, but I don’t think you have to be to answer this question. Since you are attempting to stretch the ligs, them getting tight is not a problem. HOWEVER, the last part of your post IS a problem. Let me quote here:

YES!
PLEASE PLEASE PLEASE DO NOT PULL TOO HARD. Gains will come. They will not come quicker if you pull your jewels from your body. Take it easy. Feel tension, not pain. Don’t try to rip your package off. Too many newbies (me included) think that if they pull harder then gains come quicker. Not true if you are just starting. PAINS come quicker but not GAINS. Don’t injure yourself. My famous (only because it has been quoted once…notice the big head NOT on my dick) PE is a marathon not a sprint. Take your time and do it right.
