Well, last I remember, you were about to pull a maneuver with the shower? Then got sidetracked with him coming home late. How about approaching that again. It's a nice "start" to things again. You're not just jumping back into things.
Keep in mind it's more than just starting to have sex again. He said he feels that you're not attracted to him (not "into" him). You feel poor about body image, etc. So, take small steps toward that goal--Comfortable. Be good to you and him.
I like the shower idea. Nothing even has to 'happen' in with the shower....even just jumping in, talking, and being together naked is a HUGE start and HUGE breaking of comfort levels. Don't get disappointed, or have high expectations. it's hard for both of you. Just set low goals....get just a little comfortable and intimate, have a good time and relax. The last thing you want to do is be uptight and make him feel that way.
Why not be creative about timing instead of making it a "talk" that kinda takes the fun out. Just start with little steps and the rest will come. Heck, you did it before, it's not like it's something that's new for either of you! Remember that. Relax and enjoy!
