Me and my boyfriend has sex for the past two night.  The first night he didn't have any condoms so we fucked raw . He came like 4 times but each time he pulled out and whipped his penis off. With me doing some research I realized that their still could have been some sperm slip through. So the next morning I took plan b.  And last night we had sex with a condom! It popped on us but he noticed and changed it before he came.. so I'm jut kinda nervous. Any advice on if the plan b might help
