Mine has held up nicely. I even pull on it real hard every workout to get some length workout.
According to the gauge on the Bathmate, I gained about 1/2”. I also fill the tube completely in girth now. When we do the deed, wifey can get quite a look on her face trying to take it all in. Especially with a quickie. I have to be careful or I will really hurt her.
Also, Magnum XL condoms do not fit me well at all anymore, girth-wise. They have become very hard to get on. Length is of course fine. Wifey likes me to wear a rubber most of the time so she does not have all that stuff in her at night.
I have completely given up on regular condoms. They just will not go on without a lot of work.
