Yes, I use them all the time.
If you graduate to the full metal cock and balls models you really must follow the rules for putting them on and removing them.
Always balls in first, warm ring with a bit of lube, then ease in soft cock.
Removing just reverse the order. Cock out first Always!
Very hard to remove if you still have a post come stiffy.
Wait a bit then gently squeeze the glans to push the blood out then pulling on the foreskin ( if you have one ) push the penis through. Balls will then just drop out without any pain.
