A few weeks ago I had protected sex with a man I've known for sometime...I'm a woman. After sex, I noticed that he put on the condom all the way...didn't leave room at the tip. When I looked at his penis, I noticed that the semen was in the front and along the sides of the condom. He was sure that all his semen was in the condom but I'm still worried. What are the chances that semen came out of the condom?
