Last night was a great PE workout , I did all my manual stretches 7 stretches min long hold , twice. The last BTC stretch , I up the time to 3 min long stretch with more of a tug and back little hunch back. The concern is last night I felt a little snap on top of my shaft near my fat pad. I believe I read something about short ligs snapping , buy not sure if that is what it was. This morning a had a awesome hard erection , but all day today I have been sore on my fat pad , all day. That concers me a bit . Should I be?
