You're going to have to drop that attitude to work through this. I know exactly where you are coming from...oh boy do I ever know where you are coming from. But IMO you just made it sound as if you will do all the talking and then it's up to him to do the work....that's not how this works (if that's what you meant).
So nope, don't start your conversation that way.
Start with how this lack of attention is making YOU feel...ignored, unloved, angry, sad...etc. Relate it back to you and how YOU feel.
And GOD do I understand how you feel!!!! Been there, done that!!! Went for 12 months without sex at one time myself; before I put my foot down with my H we had managed to ML 3 times in one year woooohoo! With him I literally had to tell him we had to do something or we wouldn't have another anniversary....BTW, we just celebrated our anniversary!
I suggest you let him know you two need to have a serious talk....and then lay it on the table for him. Try, try, try....not to get angry with him, that's likely to just shut him down. I know I stop listening if someone's yelling at me.
