rather than words use actions, run her baths offer a massage take off her shoes when she comes home,little treats tell her to rest while you cook a meal,tell her how much you like to make her happy and hope she's proud of you.
most people if they have a Dominant side however mild will over time automatically respond accordingly to anyone with a submissive nature. gradually show her your sexual interests show her things on the net, i wouldnt introduce her to bdsm sites and the like for a while it might scare her off just accidently come upon a few mild bondage type pics and vids.

a good one is if you're going to a fancy dress party, suggest matching outfits such as latex/rubber skirts with cheap whips boots and the like for her and dogleashes leads cuffs etc for you..all in the name of fun ...then when you've had a few drinks go home make a joke of it and suggest fun in the bedroom with the accesories thats worked for me before using a little light persuasion.

but remember you cant make someone be something they're not you'll just have to follow your instincts.

good luck

i wont suggest a gimpsuit,i dont know what the hell one is lol
