I reccomend number closing with sharpies, Iv number closed with a couple girls and it was fun. one of them drew a penis though and we joke about it.
but it is fun to write on someones skin and if its them having fun right before you take off itll definetly help out.
way more better than unlocking your cellphone and making her wait. just take out a sharpie from your pocket and let her write on your skin.
also say "ITS A GOOD THING YOU DIDNT DRAW A PENIS
" she will most likely draw a penis and laugh about it.
