weird feeling during sex?

So eveytime i have sex with my bf i feel uncomfortable in my vagina like a burning sensation,it's so weird because I'm always super wet and we use alot of lube also but it's still there.I tried to touch around my vagina and the feeling comes from this certain spot and i guess that is basically the g-spot or something
Maybe it just could be because those were the very first time I've had sex idk. I really want to enjoy sex but for some reason that has to happen
