I have now found out that Frenulum is too short, i can get the foreskin all the way back when not erect, but when it grows i cant get the foreskin back over the head completely, gets to about 75% back.
but ive been told i can stretch it, but im nt sure how to. i dont want to snap it :s what would happen if i pulled the foreskin back when not erect and then get a hard on, would i run the risk of snapping it?

Thankz
