Does this sound like an STD?

When I have sex with my boyfriend it hurts - everytime. But only when it is going in. After he is in, I am fine. Occasionally there will be a little blood after sex. Now a lot, just when I wipe after peeing there’s some on the towel. These aee the only symptoms I have but they have me worried about an STD such as chlamydia. are these issues normal?
