Is it bad that I laughed at dirty talk during sex?

I thought it took off some of the pressure inseam of taking things so seriously. This guy I’ve been seeing started talking dirty and I just burst out laughing because I couldn’t take it seriously. He seemed like he was trying to brush it off and laugh with me but Im afraid I hurt his feelings. My friend said that you should never laugh during sex, especially during dirty talk but that sounds like that would be fucking terrible. Am I being insensitive because I laughed?
