I have been looking for some cock rings that are "snug" enough to hold my erection during vigorous sex in "tight" situations. These Titanmen Rings are the best I've found anywhere, and the price is right. A person can spend much, much more for those "snug" enough from manufacturers of VED devices, but these work just as well. Since there are 4 in a package, I will sometimes double up on them, using 2 at once. Thank you Titanmen
