Pain with sex

Sophia

I hooked up with an ex fling last night and there was so much build up to it and then we had to stop because I was in so much pain. He was really nice about it but I can’t help but be embarrassed. Want to redeem myself in that department and have it happen again. I genuinely think I just hadn’t had sex in 6+ months. Not an issue of dryness more of tightness. Has this happened to anyone and what do I do about it
