What Happened To My Sex Drive?!

For the past two years my husband will not have sex with me unless I initiate it. It seems I rejected him one night years ago when I couldn't continue an all-weekend sex bender he planned, but I didn't get the memo. 😑😄 He was a little hurt, we talked about it and I thought things were fine until we tried to have sex some time after that and he couldn't follow through. He said he'd been masterbating in the shower since I wasn't giving it up. I was hurt, but made an effort afterwards. Ever since then, sex has been awkward which seems it has really messed with my head and apparently my heart. I can't seem to get them on the same page and when we do have sex, foreplay is dull. I miss the connection and desire to have him. I love my husband with my entire being. I want to be the sexual goddess I once was and leave him properly sated. Any thoughts and ideas will be greatly appreciated and helpful! ❤
