I'm not sure about how to rekindle the flame, but I have found men are attracted to women who are doing their own thing. My advice would be to explore things you are interested in and get active in pursuing them. Crafts, reading, history, art, whatever you're into. The more you seem interested in life and living, the more attractive you naturally become. Cheesy, possibly, but it does seem to work. Sometimes sex isn't the most important thing, anyway, if you have a good emotional and intellectual connection! I personally have never had good luck with the lingerie-seduction method. I also agree about the health check-up!
