I have been having a lot of problems having sex with my boyfriend. I am 19 years old and we have been going out for about 3 months and always use a condom. The first time we ever had sex I first had a burning sensation upon insertion and then we added lubrication and it was okay, except if he went in too deep. But then when we tried to have sex again it felt like a stabbing sensation upon inserting his penis in my vagina. Even just a little bit hurt so much. I went to a doctor and was diagnosed with BV and was medicated. When BV went away, I got a yeast infection and was dealing with that for over 2 months. When that went away recently (I was checked: No signs of infection of any kind) so I was FINALLY able to have sex with my boyfriend again and then the same thing happened the last time we had sex. Please help

I think you either have an STD or an infection I suggest you consult your doctor before having anymore sex.
