Comdoms are definately better than not using anything. However, I had one to break. That was scary. Forunately, I didn't catch a STD or get pregnant. I don't know about other ladies, but I had a situation when a guy was determined to use a MAGNUM. However, he was not large enough to accommodate that large of a comdom. I didn't want to hurt his feelings by telling him to his face that he was too small. I was NOID about the condom slipping off. We started arguing about it, and I just left. His ego was a bit crushed, but I just had to tell him. He wasn't small but no match for a MAGNUM.
