Problem with vagina tearing during sex, using lube

Im not sure what this is but it looks like a tear happened during sex while, despite being aroused and using lube. It doesn’t burn to pee nor does it itch but i just noticed the tear after sex. I check my vagina often to be sure everything is in check too!! Is this worth seeing my gyno over? Also its right in the opening of the vagina. It doesn’t hurt thank god only when i first touched it to see. Also its not a raised bump just a cut!! Any recommendations to heal up this tear?
