Does anyone else have the problem of retracting testicles?

The left testicle is the one that gives me problems. It goes inside from time to time, and I once was scared that it wouldn't get out at all after a full day's absence. It was scary nightmare material when I first noticed it.

I have this exact problem. If it goes inside me i have to push it out instantly. When having sex or something, i never do it under a bed sheet or anything and i always get a bit cold so they retract due to temperature. If a girl licks my balls at this stage my left one just pops right inside me and i hate it so so much. I freak out when it happens. I near enough throw the girl off me and get the ball back down. However, pumping my balls and massaging is helping them hang lower. I pump with my Bathmate at LOW intensity. It feels good and they get bigger and hang a lower after pumping.

I have the same issue on the right side. It's difficult to find any solutions. Most say that it's harmless so don't worry about it. The thing that bothers me about this, other than the look of it when it slips up there, is certain sexual positions. When she's on top and I'm fully inside, that hip rocking motion that they seem to like forces it to pop inside followed by pressure on it from their weight. If I don't fix it, it'll pop out forcefully also. Very uncomfortable and natural reaction forces me to "jump" even if I know it's about to happen. And then they wonder what happened.

I looked on a couple ball stretching sites and even bought a leather 1" stretcher. The hardest part is getting it on without pinching. It probably takes me a full 5 minutes due to one ball hanging right and the other being so high. I have trouble using with any regularity because it hurts after a bit also. I've considered trying one of the weights also but not sure if it would be any easier. If one of y'all try it, let me know.
