He places one restriction for himself due to lack of interest: anal. He generally leaves that part of my anatomy alone. Everything else is fair game.
It is not so for me. Sir is wired differently than me, and different than other men I've been with.
I am not allowed to touch his hair. Ever. He let me touch it ONCE, a couple of years ago. And he let me wash his hair once or twice, for the service of it. Other than that, I've not run my fingers through his hair in the 4 years we've been together. I still forget sometimes, and stop my hand halfway from his head.
He is also very disinterested with his ears being touched/kissed. It's not forbidden per se, but he obviously gets nothing out of it, so I avoid that area too. It's odd for me, because that area drives me crazy! Same with his nipples - it's like he couldn't care less when they're receiving attention.
I also typically avoid his feet, because he doesn't like his feet. I don't mind them, I just want to service them so he might like them more. He's not forbidden me from touching them, but he has said that he doesn't like it. Not for the sensations exactly, but I suppose that because he doesn't like them, he doesn't want me to be around them close up?
Are there places where you're forbidden to touch?
