I also have a somnophilia kink. My sub and I have a 24/7 dynamic, and she gave me consent to do what ever I'd like to when she's asleep. I just usually accidentally wake her up accidentally trying.
That may actually work really well for me, honestly. I never really considered it.
I do this a bit time to time. I know she's ok with anything I want. We dabble in cnc sometimes too, but only barely. I can definitely objectify her in my head. When I try to enact those things in person I kinda freeze, or talk myself out of it. Maybe it's a confidence issue? Sometimes I'm scared Read more… ill do something she doesn't like and she'll be upset. Though rationally I know she won't, she'll just safe word me if it's too much, but I think past experiences are keeping me back, too.
