WHATS GOING ON DOWN THERE😫😱❗️

Ka
I had sex Wednesday morning I've had sex 3 times all together previously and now I feel like my vagina is loose because my vagina is like "queefing" ig idk if that's how you spell it but it's like sucking in air. We had really hard sex and I'm on my period ATM and my tampons are going in with ease and it's never been like that before I'm confused on to what's going on down there.
