I love Okamoto Skinless Skin condoms; they are AMAZING. If your guy is REALLY big, however, you run the risk of them ripping, since they're smaller. If that's the case, I stick with Kimono microthins.
I really don't worry about condoms ripping because I tend to test a brand out with toys before settling on it for sex. I also use birth control pills and get myself and my partners tested regularly, so my chances of getting an STI or getting knocked up are slimmer than most.
