As a guy, I say your right he is wrong. He should share his wants with you. As for your 22 year old daughter, creepy. Now if you truly have an open relationship in the aspects you are intimating here. I need to ask, why did you look at his phone? Does he do that to you? Is there under lying jealousy that needs to be brought up. I hope you work through this with him. I definitely wouldn't do this to someone I am dating, but I would also want to have a bit of privacy in some aspects. But be open and honest with each other, maybe he was doing it for you, or he just needed a new perversion. Stay strong and I hope that you can work this all out.
