Okay so me and my boyfriend have started having sex but before we have sex he fingers me and stuff but I never know if his hands are clean from pre cum and stuff. Then we end up having sex and he never finishes inside me and we use condoms but I'm always paranoid that it would be just my luck something happens to me and I'm going to the doctor Tuesday to get BC and I'm scared they will tell me bad news, can anyone give me advice and calm my nerves.
