I belly kiss one boy.. the other one always smells like pee... my lips do not go there. I swear he purposely pees on his own belly! Fresh from the groomers, after one pee he smells like pee! haha so nope to belly kisses on him... my other boy though hes super clean, always cleaning himself and smells good... so he'll occassionally get kisses on his chest area! Not really belly but he does have to roll over for them!
