So I (31M) have approached, dated, and escalated with girls as young as 22 years old and have been okay with that. Yesterday, however, I approached a very attractive (tall, fit, and exceptionally beautiful) girl who looked 22ish, but turned out to be 18. When I found out, I excused myself, mentioned my age, wished her good luck, and walked away. But 10 seconds later I just walked back and said "Fuck it, just grab my number and text me if you're into me." She did! Nowz I can't help but think that when I was 20, she was a first grader! Dating and flirting with her thus doesn't feel right, and I'm considering excusing myself again and stop it. I'm hoping you guys can help me decide. I'd appreciate your thoughts.
