It does not hurt. In fact you forget you have it on right after you put it on. After two or three hours, I do feel it and it may be a little painful if I have it clamped down real tight.

They recommend you do not wear it for more than two hours in one spot. By then you should pee and just relocate it a little bit.

It has three different size rubber “gaskets” you can switch out. So you pick the one that you can clamp down the furthest without hurting yourself.

One guy in this forum, said that he wears them all day. He doesn’t tighten them down completely and wears a pad if he leaks a little. I prefer to tighten it down all the way.

It’s not very expensive so it’s not a big deal to try one out. I’ve used a couple different brands and the Wiesner works the best that I have found.
