Massage Question

I love getting massages. 60-90 min of pure bliss. My partner doesn’t like me getting massages. He says he can do the same thing but when he does it last about 15 min top. I am nude during the massage with dropping over me. I don’t get a happy ending. Some days I just want to go after a long days work but I feel like I’m doing something behind his back. Ideally I would like a 90 min massage twice a month. Am I being unreasonable?
