I suggest you just take the batteries out, pack the lube in a plastic casing of some form (ziplock, tupperwear around the bottle, etc) in order to prevent leakage, and if for some reason your stuff does get searched, just giggle and tell them that you're on your honeymoon.
Or, get a box and write on it with big letters "OUR SEX TOYS" just so they know it's not a bomb.
