Anyone know what is most likely to cause this? I've had two condoms break in my life and well, I've had some experience but I really haven't had a -ton- of sex all things considered. I'm pretty confident that I put the condoms on properly but I'm starting to get worried. I've always thought I was sort of just an average size guy but been told otherwise a few times. Now I'm wondering if the condom might just be too small? What other factors can play into this? I think the most recent occurence was because we went too long and had no lube. Yes, I read the condom stickies just didn't really feel my questions were answered. edit: normally use trojans (spermacidal was the one that broke on me). Most recent was a durex performax or something.
