I had the same problem twice. It tore partially the first time and the next time I had sex it tore all the way. Both times I just kept it clean and it healed with no problem. I think that frenuloplasty is needed in only a small percentage of cases. For an uncircumcised penis unroll the condom some and take about inch of the tip between your left thumb and forefinger. Hold it flat as you roll the rest of the condom on - that gives your penis room to push out of the foreskin without putting a lot of stress on the condom (and maybe breaking it, which happened to me once when my partner became very aroused and active).
It only gets worse!!!! this happened to me, same thing. after it rips it will heal. however, the scare tissue is less flexible and more brittle. so basically, once it happens, it keeps happening. the only solution is something called a Frenuloplasty. see your doctor. also visit this sight. http://www.circumstitions.com/Frenbrev.html
