Yesss, girls get very ashamed if anything "abnormal" happens with their bodies especially during sex or anything sexual (bleeding a little bit, that sloshy noise when they get wet, involuntary groaning, ect) , but try and laugh it off with her, that's the best thing I could think of doing. It's not a big deal, she's just sensitive, especially if she's younger/hasn't had sex/done sexual things a lot.
