Sex - Vagina pain

So situation is, I only have sex once in a blue moon kind of thing, once every few months now. Everytime his dick enters me for the first few minutes it's painful especially when his dick first goes in, as if it's the first time I'm about to have sex with a big dick and for some reason I get so nervous and scared a lil cause I know it's gonna hurt yet after a few minutes in it feels normal.

Any females here experienced the same feeling?... Maybe it's supposed to feel that way after not being fucked for months at a time huh lol

Defs going for a check up or smear test once this lockdown is over.
