I just purchased a Sperm Stopper "penis head glans ring"
http://www.extremerestraints.com/sperm-stopper-penis-head-glans-ring_1398.html

Its a glans ring with a bead that plugs the uerethra. I havent tried it yet, but am excited of course, and would like to try it during regular sex, but I dont know how safe it is for me or my wife.

Has anyone tried this or a similar product? Does anyone have any thoughts on problems this could cause?

Were not really that kinky or into BDSM, but we also got a blindfold and the following.

I think it will be a fun valentines weekend!

I can't speak to this particular product, but I do have experience with rings that fit behind the head. I've learned two important things:

1) Make sure your head is big enough to keep that ring in place. Friction and lubrication work against you, and it is verrrry embarassing (and quite a mood breaker) if you have to tell her you need to go retrieve it from inside her! I speak from experience there (it IS kind of a funny story--I might recount it here later).

2) Those little ridges on the stopper that connect it to the ring might be sharp on her sensitive parts. Go slowly. And that includes pulling out. You'll know pretty much right away whether it works from her.

That said, I've been curious about this product myself, having been a purchaser from XR in the past. Please let us know how things go!

So i recieved my sperm stopper, after using it a couple of times myself, Its not that great for me. If the ball is not in the best position it hurts a little, and im not one for messing around too much in my pee hole. it is kinda fun, but when you cum it just slows it down a little and oozes out around the sperm stopper. anyway here are some real pics with the sperm stopper on
