I agree with Jayanna. Say you don't have their permission. Or actually ask their permission if you wish and see what they say. If they're ok with it, fine. But only if you're ok with it, too. If not, just tell him they don't want you to give it out. He can, of course, always ask them himself, but probably won't.
Idk if he's trying to control things or just trying to show an interest in your friends. Some women complain that their men aren't friendly to there pals and maybe he's trying to show he's not like that.
How is he in other areas of your relationship? If you feel he's too controlling or pries too much, in the main, maybe you need to rethink your friendship with him? If everything else is ok, then carry on, of course.
