Hey Oysteinn. I had the same problem man. I bet by now you’ve tried many things, and I don’t want to repeat what everybody else said, so I guess I’ll lend some minor suggestions.
I got pretty bad turtling after sessions, not even just visibly smaller, but I could feel it. It was very uncomfortable, and would last a while. I’m not sure what did it for me, but I changed a couple of things and it got better.
-Make sure you’re warmed up good. Maybe even watch some porn with the warm up and get an erection and get your unit ready.
-After stretches, I started doing another hot wrap. Not inconvenient at all, because I massage it at the same time and get it plumped up for jelqing, and at the same time I’m keeping those tissues warm and pliable.
-During warm down, watch porn. Keep at least a semi erection.
If all this doesn’t make a change at all, try adding a cool down right after your warm down. But keep a full, 100% erection during the cool down (watch porn, massage. Make the warm, pliable dilated tissue stay in that expanded state by cooling them.) Might make a difference. Take it easy and keep at it til you get it bro. Good luck.
