Last night I was doing a jelqing session, nothing to routine just feeling it and doing what felt right. The room was dark and I couldn’t much see what I was doing but after I was done I went into the bathroom and noticed I had what looked like a huge bubble on the side of penis below my head. I was freaked out seeing this since I’m pretty new to PE. I went to bed last night freaked out and this morning when I woke up the bubble is mostly gone but now there is slight pain when I touch the area and there is excess skin that now is there. My question is has anyone seen something like this happen before and if so how long did it take for the pain/bubble to subside?
