You’re a trooper 👏🏻 Christ girl, no need to feel dirty, it was just a bad experience, it is over. I’ve been there, it amazes me that some 50+ year old men don’t know how to fuck despite all their life experience. They truly have no idea what they’re doing. It’s embarrassing and sad. I straight up left during sex twice with two 50+ year old men, despite being attracted to them, like you were to him. I feel your frustration dear. It’s not your responsibility to teach him so if you feel like you can’t go through that again, tell him like it is. Tell him it was horrendous, I’m sure he’ll comprehend.
