Hey guys, a bit of a problem here.. Magnum condoms seem to break when I use them during sex and I'm not really sure why. There's nothing really specific that causes it to happen. This is the second person its happened with. She is pretty tight, but not ridiculously tight or anything so I don't think that's the problem. They've broken when I'm on top and when the female is. There's plenty of lubrication and I always engage in PLENTY of foreplay before the act (at LEAST 20 minutes, always). I'm not too aggressive and neither is my partner or the partner before her. Also, sometimes during sex I notice the condom starts to squeeze vertically.. not really sure how to describe it. Kind of like a slinky I guess? It gets a little tight. So my question is, why do they keep breaking?! I googled some info about condom sizes and it says that you should only be using magnums if your girth is 5.25-5.75 or so.. I'm at 5.5, and my length is about 9. However a diagram of a magnum also says they're about 1.5 inches WIDE.. I'm 2. (I always thought it's weird how I'm 2 inches wide but 5.5 around...). XL's are 1.75 wide but for people with 6 inches of girth, and again I'm 5.5. Should I be using XL's? People my size or even a little bigger here on LPSG seem to be using regular Magnums so I'm not sure. What's going on? Thanks for any replies!
