Guys - Ever been caught or exposed in your underwear?

When we have been on the beach all day and it's time to go home, I pull off my speedo and take a shower. There are several showers right on the beach, and my mom comes with me to help get the sand off. When I'm dry after the shower, my mom holds my underpants for me to step into, Then she pulls them up on me. I feel a bit embarrassed standing there in my underpants as I think maybe a lot of people are looking at me. When I look around there are some people watching me, but there are also some mothers getting their sons dressed.
