"I want to get to a place where you can do whatever you'd like without worrying about that. I admit I'm probably not there yet, but - it's important to me." He'll reach for him and just - hold him - he is sort of worried that Telumë is missing the spirit of 'I belong to you' here -

Telumë is having to do some internal adjustments here, trying to find the balance he can hold. This is - sort of inevitably going to involve some things being uncomfortable and concerning, because the situation is awful, but the simpler alternative of killing Maitimo is not less awful.

It's complicated because he didn't want to own Maitimo in this way - he wanted them to be equals, allies fighting the same fight together - but that's not an option. The part where him controlling Maitimo is not actually a game makes a lot of the previous games they played seem way less appealing, but also it will just be sort of unsatisfying for both of them if he's always being very careful.

(Also there's the part of him that is scared and lonely and wants Maitimo to tell him everything will be all right, to help him make it come out that way, and he can't have that, actually, he has to separate out some things that really should go together, and only try to hold onto the parts of his husband that he can...) 

He can maybe be Maitimo's ally in this one shared goal. Which means providing him with the set of incentives that make this possible at all. If that means acting like Maitimo is his property, then he'll do his best. 

"We can work on that," he says lightly. "I have some ideas."
