Hi Good Day ! I'm 20 Years Old And Love

Hi good day ! I'm 20 years old and love having sec with my boyfriend but Is been 3 weeks I didn't have sex with him cause he was away. Now he came back we had sex 3 times but for the second I bleed and I realized that my vigina burns on one side during sex and it hurts a little bit but I can't deal with the pain but I don't find it normal. And for penetration I get a pain. And my vigina feel sore when I pee it kinda burns a little. Do I have a vigina infection?
