Cock Cage/Chastity
I have one that I wear sometimes at home. It's a medium size one with a cathiter that is about 4" long. I love the feel of the cage hanging there. The cathiter is about 8mm dia. and I'm using sounds to increase the size of my hole so I can wear that as well.
I have a couple of cock cages. One is wire, so my stunted dick shows. The other is solid metal with a cougar head at the end of the shaft. Looks nice but it's pretty heavy. I've worn it a few times at sex clubs and bars with jock strap night. Have had some solid times at the baths focusing totally on pleasuring a guy without any possibility of stimulating myself. Mind blowing.
A couple months ago I was at a bar jock strap party and there was a guy there wearing only a harness and a cock cage. It turned me on because I knew what was going on in his brain and his trapped dick. It was a pretty crowded event. Even tho there wasn't supposed to be any sex, I did see him taking a dick up his butt, and giving a couple blow jobs. Total turn on.
