I ditto everything heather said :)
good luck! I know it can be tough after trying to rekindle the relationship after a falling out.
have you guys thought about going away for a romantic weekend? a hotel room, champagne, chocolate covered strawberries, sexy lingerie...the works? or try playing a "sex game" (spencers has some great games). role play...etc etc etc. spice it up in the bedroom...it might give you what you need to get into the mood again.
