FTM and almost two year old question

Okay so first off I want to make it clear that my husband and I try not to watch anything with romantic scenes in it or if there is I fast forward it. We also don’t make out or anything in front of our daughter. I’m a stay at home mom so she is with me 24/7.

With all of that being said, our daughter keeps trying to make out with us and she humps our arms or legs when she is tired. I don’t know where she would’ve learned this. We always redirect her and tell her we don’t do that to mommy and daddy. Is there any other way we can teach her that we don’t kiss like that? I know the humping is natural for kids to do and it’s a phase but what else can I do to teach her we don’t do that to us?
