I came across something today that I had never seen before, hollow strap on dildos. They are hollow at the base for us to put our dicks in. However they are big 9, 10,12 inches and available in realistic black. I've been on sites like this one for years. However I have not seen posts about these. Are they just too weird or feminine for people? I think this looks like an interesting toy. Has anyone here used one?
