Does it bother you when people sexualize something a baby or young child does?

Today I sent my long distance friend a video of my son using my head to balance as he stood then he bent down and gave my cheek a slobbery kiss, but while he was standing and wobbling his little bum/crotch was level with my face and she said "oh my God that looks so wrong from that angle!!" Am I being oversensative that that kind of crap bugs me? She's also referred to him climbing over a stuffed animal as humping it which also bugged me and I just said ahh don't say THAT and laughed it off. But like it keeps happening. And it's not just her, am I the only one bothered by this?
