I'm not sure if I'm being a prude here so would appreciate your perspectives. DP is very affectionate - too affectionate IMO. He can't pass me without touching or kissing me, every time the car stops he wants a kiss etc. Obviously the DC are in the back of the car and I don't like the idea of snogging in front of them. Being asked why daddy sticks his tongue in my mouth/squeezes my bum/looks down my top etc makes me cringe. DP thinks it's good for the kids 'to see we love each other' 
Who is BU?
