Can't think of one

You only laugh when I occasionally belch
You politely ignore my sweaty feet going squelch 
You giggle discreetly when I sometimes fart
You've yet to see me when I eat a tart!

I don't yet scratch my nuts at dinner
And itching my arse is always a winner
You hug me when I haven't shaved
And squeezing my zits is really brave.

You listen to rhymes about my poo
And a snotty nose is nothing to you
So now you know my armpits spell
And there's mould between my toes as well

But this is why I love to share
All those bits of pubic  hair
I love you because you make me laugh
And yes I'll have my monthly bath.
