I'm having real trouble locating what I see to be a good butt plug harness. All the ones I see have a dinky little strap (like a thong) in the rear, which doesn't seem like it would be effective to me. One I have found that has a wider panel in the back is this one. Unfortunately the site doesn't have a valid security certificate, so I was worried about using my credit card! Also, how do the ones which have a cock ring at the front work with a CB? Is there too much in the way? Does it push the CB too far forward? Help please?!
