Sharing Toys
How do you feel about using a toy with a partner that they have used with a previous partner?

Wearing a cock ring
What is the proper way to wear a non vibrating cock ring? I have seen some where instructions tell you to just wear at the back of the penis against.

Do you enjoy wearing outfits that take you a bit "out of yourself"?
Do you like pretending/imagining/b eing someone besides your casual self when you put on some fancy wears?

Do you like string cheese?
It's been my go-to snack lately; I'm a sucker for it!

Pump vs Pill - which works better?
To all the males out there. Have you ever used a pump to make your self bigger? Did it work? If so by how much? Did you use pills to make your self.

Different sizes need to be offered for different guys. Not all guys are the same size. The big thing with a metal ring is they are not easily removed in an emergency. You can not cut stainless with a pair of side cutters as stainless is very hard. So my guess is that guys buy the bigger size to prevent problems. Plus it will make it easier to get the whole package, balls and cock, through.

For me a C-ring like this would be used for the "Bling" factor, not for sustaing a erection.

I had one a few years ago, and I believe it was 1 7/8. It fit perfectly and was very comfortable for long term wear of a few hours. Any larger and it would not have worked properly for me.

You need to measure. It is very important. It could just be a fluke that those that have reviewed it need that size.

It looks like it would be painful and possibly dangerous. I guess it isn't since so many people enjoy it but it would worry me.

I have the 2" Omega Engraved and the size works very well for me. 1 7/8" might be even better for me, but the 2" would definitely be my preference over the 2 1/8". The points that others have made are valid ones though.

I'm loathe to try metal cock rings but the kind that stretch can be fun.

Thanks for all the great information. I guess I'll have some measuring to do before any ordering takes place.

I actually made an error and ordered the wrong one by accident. That silly little 1/8" makes a huge difference! If they had one, I might (in a perfect world) try a 1 7/8. The weight thing is definitely WILD!

I measured and re-measured for days and decided the 1 3/4 was the size for me since i want good restriction, and live 5 min from the hospital That last part is a joke of coarse, well not living near the hospital in case of a real emergency I do live 5 min away, but I measured carefully, and bought a rather hard silicone ring of the same size from a sex shop to "test" it out. I've practiced for a few weeks and i'm confident I can get it on, and off with no trouble. I'll probably get a bigger one to wear around for the "Bling factor" as Dwtim puts it. I feel with these its all about having the right measurement, and Practice Practice Practice, You should have seen me trying to get my "tester" on and off a week ago even, it was horrible. Now I can slip in and out of that bad boy like a champ.
