aww, my comment wasn't meant to make you doubt yourself. It was a compliment really. It was saying if she was laughing so heartily you did exactly what you'd hoped to do - connect with her. If she was laughing I think it's highly doubtful that you came across as a "dim-witted horny guy". And what you said really didn't sound horny anyway. Try not to worry so much and enjoy the seduction process. It's fun and it's meant to be fun
And nothing wrong with a bit of honest dirt, go for it if you want to
