No your not being unreasonable it seems as though you do everything in your power to satisfy him but he isn't showing you that same courtesy as far as your needs are concerned, if he truly cared about you he would compromise and do it when you want to do it along with when and how he wants to do it. What you are going to have to do is sit down and try to set some boundaries as to when to do it and how you want it done. He needs to realize that having sex with someone is not one sided he has gotten so use to masturbating that he is become a some what selfish lover now because he knows he has other options as to how to orgasm. His masturbation is actually harming the relationship instead of enhancing it because he knows that if you do not give it to him he can do it himself without all of the emotion and feelings involved and may much rather do it that way than to do it with you that is why he feels as though he is in control of the sexual intimacy in your relationship and you have to take control of the situation yourself. He may have an obsession with masturbation that is emotionally making him absent from the relationship and if the relationship continues with this you may find yourself without a mate so it's important to talk to him now and not let it get anymore serious.
If both of you were to start masturbating then you both will be filling your voids without the other and that is never good for a relationship. Accommodating him in the mornings means that you too are being accommodated also so don't stopped that aspect of your life because you really have to feel some type of connection with him intimately. I think your mate needs to seek counseling for why he has to masturbate so much when he has someone like you there and willing it could be an addiction to masturbating.
If he is finding it hard to control his masturbating, so much so that it is affecting your relationship then it may be times for him to seek counseling. Especially if he has to masturbating almost daily, it's getting out of control and the enjoyment can be lost or become short lived. It can become a very negative thing if your mate is finding it hard to control it of even stop it once it has gotten out of control. If you are in that place with your mate and want to control how often he is masturbating and have tried and tried in the past only to fail, then you should turn to an approach that has stood the test of time which is either counseling or hypnosis to stop his obsessive masturbation or else he will totally replace you with his masturbation. The hours he wastes masturbating takes away from your life. Those are hours that he could be doing other things like spending that time with you in intimate ways. When he feels the urge to masturbate he should fill that time with something else like going to the gym or hanging with friends this way he saves that energy for you. The reason it doesn't last when he tries to avoid masturbating may be because he has nothing else to fill his time.
