Boyfriend's dad found USED condom 😭

I've been with my bf for over 3 years now. His parents are very aware that we're sexually active...his dad will even have little convos about it with him. I only see him 3-4 days out of the week, so yesterday we had shower sex when everyone was asleep. Although I'm on bc, he likes to use a condom when he wants it to last longer & when he wants to finish in me. Right when we were done, I felt so lightheaded that I had to step out of the shower for a min. Usually he handles the condom & will throw it away when we get out. BUT this time he left up above the sliding glass door. His dad texted him today saying he found it & was sending "ew" gifs to him.

I'm so embarrassed like I do not want to go there tonight. Is this even a big deal? Like his parents are really chill, but I'm so nervous to even step foot on the driveway tonight. Like how awkward. Idk where my bf stand because he literally just sent me a screenshot & went off to practice.
