My boyfriend mentioned the time I almost killed him with my vagina

I've been with my bf for 6 years and I was feeling insecure. I always tell him when in feeling down or insecure. He saw one of his ex's at the store and she is so much more pretty than me. I told him I was insecure because of her and he said he would be dumb to ever leave me because I got A1 pussy😏🤣. He brought up the first time we ever had sex. This was honestly my worst sexual experience ever but he had a heart attack in the middle of it. That was awkward as fuck at the hospital. Why he had a heart attack had nothing to do with me but he said "You have such a good box, you almost put me in a box." Then he ate my box. I feel better now😂
