Say something embarrassing

So my guy who I’ve been seeing for exclusively 8 months now is absolutely amazing and gives me pleasure in ways I’ve never imagined, told me something a little embarrassing the other day after sex. We tried a different way in the car and I sat on top of him facing away from him... apparently my ass was visible and I had little pieces of tissue stuck to my butt... he told me after and said he didn’t want to embarrass me but I should know... is this something I should worry about? Will he still want to see me? Meet up? Or is he simply grossed out and embarrassed?? Help need advice
