The first time I had sex almost a month ago, we didn't use any condoms or anything. He got in for 5mins or 6, then we saw blood on the bed. And we both got worried, though we didn't think about it that much.. Last week, we did it again without any condoms, but I started having light bleeding again, but it was only half way through, and we were having a hard time getting it in like the first time. Was that normal?
