Different ways to initiate sex..?

I'm kind of bored with just the ol reach around/ rub his back, then go down the shorts to start getting him up, etc.

My husband isn't as much of a hornball as I am and i am bored of initiating. So i haven't in awhile, I've just let him be the one to, at least i know he wants to at that point. But he made the comment recently that he's the only one to initiate.

So. When we get in bed he rolls over on his side facing away from me and plays his phone game till he falls asleep and I just feel like it's hard to initiate with his back to me (aside from scooching all the way to the edge behind him to be the big spoon and doing what I said above)

I've brought it up before to him but it doesn't change. Like... be more open, lay on your back at least so I can get to ya! Lol

Sending sexy pics or something, he's just kinda like "😍" and that's it lol he's definitely not the sexting type.

Got any ideas for me? I need to liven this sex life up a bit!
