It’s really difficult to know exactly how to tell somebody this, though, without sounding rude and abrupt.
Today for instance I had an arm around me and my hair tugged / played with, I had a hand on my thigh stroking, stroking, rubbing, massaging CONSTANTLY, I had him suddenly and without any warning flinging his arms around me and burying his head into my breasts/ stomach, taking my hand and stroking it.
I did not respond once in kind, I tried to edge away, but no. Surely he would notice? 
It sounds so harmless “cuddling in front of the TV” and in my single days I’d think how lovely. As it is, I have a bad back and get trapped in one position, can’t even shift position from one buttock to another!
It’s exacerbated because he is such a POOR talker! He wants to go out for endless walks which to be honest I’ve started to dread a bit because he wants to hold hands but then gives me nothing whatsoever in terms of conversation. And honestly, with most people this isn’t a problem so I don’t think that it’s me.
Then when we get in he starts to grab and massage and so on and starts “making conversation”, but he will latch on to something I said - like today I mentioned something about a certain vegetable, he then (some four hours later, while playing with my hair) murmurs “so what do you do with the veg?” Not even in a sort of pervy way, just he’s trying to make conversation and “relax” me I guess. But it’s such hard, hard work.
