Not sure if "mad" is the right term but I would not like it
The issue to me is not the product one way or the other. The issue would be not talking to me about it. That would be true of lots of things. But in sex I think the both husband and wife should be 100% open and honest and real about everything. It is an area of life that needs total trust.
The point is that you don't go around sticking things in peoples bodies with out consent. Even my doctor lets me know what he is going to do down there before he does it.
