We've had our RodeoH for a couple of months, using it a few times a week. There has been no wear on the harness whatsoever - and we get pretty rough. It isn't a cheap fabric. The O-ring is reinforced (sewn into, I believe) the fabric, so it isn't getting hurt. Your body holds the cock at such an angle that it isn't really touching the base. If you're worried about it, I guess you could put petroleum jelly around the fabric of the O-ring so it's not directly touching the cock. For me, though, it hasn't been a problem. The RodeoH works. It can definitely handle a beating. You don't have to worry about it falling apart. It's high quality and should last a long time if you don't actively try to destroy it.
