Question about boys..

Any mamas having (or have) a boy and already worried about the um.. things that go on when they get older? I’m so excited to be having a baby boy (FTM) but have never really been around boys, I have a sister. And I’ve heard that boys can be pretty uh, gross? when they hit puberty? For lack of better wording hahah 😝 I don’t mean this in an offensive way whatsoever because I already love my baby and feel blessed to have a little boy on the way! Just already wondering about that.
