Soooo embarrassed!

So I haven't been having sex lately and I've been so frustrated! My boyfriend had a long day at work and was tired so I understand.

His nephew and him were watching tv in the living room and I was trying to go to sleep. I couldn't, so usually when I play with myself it makes me sleepy, I did just that.

Twenty minutes later, my bf comes in mad saying they heard me moaning and it was embarrassing...

I'm so embarrassed. I probably shouldn't have done that while the nephew was there but I was in my room and they had the tv on. I wasn't being loud either!... but I guess I was?

He ended up telling me that they had muted the tv because they were talking... it's my fault :( I just wish he would've told me to shush or tell me that he could hear me.

I feel so bad and awkward :( the nephew is staying the night for a few days and idk I feel weird in my own home. I'm so stupid....

Would you apologize?
