Worst consensual sexual experience

What's been the worst consensual sexual experience you've had. I remember going to a guys house the first time and his room was an absolute mess. He tried to have vaginal sex, but his penis went limp. Then he just masturbated to relieve the pressure, and his technique was so odd. Then he surprisingly came onto my stomach. It was really hot and watery, like too watery. Like he had been masturbating all day. He was too lazy to even cleanup. He was just disgusting. That was the last time I saw him!
