thank you for posting this here, I wanted to reply to the one in womens chat but I didn't want to get chewed out or anything.
First I would keep asking questions, get to know what his ex did so you can get a real grasp on it.
Making a person feel needed is not a hard task. When you have a problem, go to him first...talk things out and let him know how much him being there means to you. Be the initiator of things, even things he normally does.
As for lovemaking, whisper things in his ear. Tell him how much you love him, that he completes you, that he is amazing...etc. Try to change the routine around, try new things during foreplay. Give him a nice massage then start kissing down his back and all over, and if he shows that he enjoys it, don't let him roll over and take you...keep him there and show him that you enjoy brining him pleasure. Also when making love, try to be more verbal. I think that's a big turn on for both genders.
