My gf and I had sex the other day, and after she went home, she called and said that she had wiped with a piece of toilet paper and that a small amount of pink was on it. It happened about only 10 days into her cycle. What does this mean? Could it be from me injuring her by being too rough? We had sex once, then stopped, I went and washed off my hands and penis very thoroughly with hot water and soap, later had sex again 30 minutes later, and then stopped. We always use condoms, and I know for sure that neither broke, and I also still pull out even if I'm wearing one. I went up and thoroughly washed my hands again. I ended up fingering her around 30 minutes after that, but my hands were completely dry. Am I overreacting?? I'm very concerned.
