Really need help im so embarred. l farting?

Me and my bf were having , there wasn't enough lube and it got dry in there and air got trapped and i released air from my (simply air) about three times....between positions and when he was me. I dint know what to say when it happened. I just kinda laughed even though i wanted to cry and he laughed too and said "gross babe" but now every time i see him or what not im just embarred. I feel like im gross now or that he wont want to have with me. I want to explain to him what happened but im too embarred. i don't know what to do i don't know why im so embarred.
