Did you ever consider that he couldn't finish because he put too much pressure on himself? You're an older, more experienced, desirable woman. I'm sure he wanted to make a great impression. Once a guy puts pressure on himself to perform, it's probably not going to go well. I agree that, when a guy can't finish, it's about him, not about you. You're obviously sexy enough to have drawn this young guy's attention! Yaay, you!! Focus on that and chalk his "issue" up to youth and inexperience.
