Bleeding after sex

Okay ladies I was a virgin until 2 weeks ago. But me and my boyfriend live far and we only see each other 1-2 a week and thats on weekends but every time we have sex after when i go to pee i bleed its not crazy gushing blood its like drops of fresh blood. Is this normal. I feel like every time i get stretched and since there is a week break in between i go back to the same size and i bleed when i he enters me every time. I am scared id this normal?
