Here are some concrete ideas:
-Play footsie under the table
-Make dinner in JUST an apron
-Come up behind him and initiate a sexual encounter when he’s least expecting it
-Try doing things in an unexpected place: a park, a janitor’s closet, in the woods, in a relative’s bathroom, or in an airplane bathroom
-Play strip poker
-Give him a strip tease
-Have phone/text sex
-Send him naughty pictures of yourself when one of you’s away on a business trip.
-Suprise him at work for a quickie
-Come home early and dim the lights. leave a trail of clothes/candles/flowers leading up to the bedroom and wait on the bed in your underwear.
-Buy some new, really sexy underwear. Or even a sexy costume
-Try role playing
-Dance dirty together in a night club
-Eat food off him
-Be his love slave for a night and let him do whatever he wants to you, even take orders
-Talk dirty to him
-When he’s watching tv, go down on him during a commercial break
Anyway, have fun and just keep practicing!
