Need help!!

Ok ladies I need some help. Due to my past with guys, I've never been treated very well and have finally met someone who does all he can for me and I adore him, we live together and are engaged, however as much as I'd like to be in not overly romantic and I have no idea how to do romance and seduction. I have no idea what a man would like etc. Does anyone have any advice as I would like to do something for him Saturday evening. He likes me to dress up for him so I can do that even though my self esteem is so low that I have no confidence in being seductive and the kind of things to say etc... really any help will be greatly appreciated.
