don't buy a ---ring from the drugstore, the disposable ones that are made by Durex or Trojan SUCK. They're weak. And for those of you who are using them to assist yourselves in the orgasmic sense, I'm someone who can be easily taken care of for the most part, so when I say it didn't work for me, please be damned sure it won't work for those of you who are having a harder time. Your best bet is to visit an adult store and get one that you can keep and reuse, you just wanna clean it or hello nasty yeast infection for BOTH of you.
Funny story, my friend works at Hustler, and there's a strict NO RETURN policy on any sex toys for obvious reason. So before you leave the store, they put a battery in it and turn it on to make sure that it works, because then you have no reason to return. well, she was working and someone wanted to return a "love" ring, and it was horrifically mangled. Of course she wasn't gonna take it back anyway because it had been tested and it definitely didn't look like that when it was sold. So she put on a rubber exam glove and looked at it, curious about wtf this person did to it. well to put it delicately, it was a tad too snug for her partner (lucky bitch) and it was causing him intense pain because it cut off his circulation and he described it as feeling like "if he came his penis would explode." So in the midst of doing the deed, she had to carefully cut it off of him. Since the sales girl didn't mention that it wouldn't fit every size of man, she figured she was entitled to an exchange at least. My friend can't do that, honestly the register won't even allow it, so she gave her 50% off of a slightly larger, more elastic one. Best story I've EVER heard.
