Bleeding during sex?

Patient: I started having sex with my boyfriend in May. I hadn’t had sex with a guy before, and I experienced a lot of pain at first. It gradually became more comfortable, but there was a lot of blood. I figured that wasn’t too weird for my first time, but the second time as well (a few weeks after) was very painful at the beginning and did get better, but again, there was a lot of blood. After both times, I’ve had pain in my lower abdomen and spotting. Is is normal for there to be blood after your first time, and could it possibly be due to a lack of lubrication as opposed to a health issue?
