Unhealthy intimate relationship!! Help

I have been with my husband for 5 years now. I'm 46 and he is 48.
I'm deeply in love with him and I know he loves me too however I feel that our intimate relationship has been unhealthy for few months now.
I feel like he wants to have sex only when we are drunk which I absolutely hate. We are social drinkers so we normally don't drink at home or during the week and definitely we are not out every weekend so we are intimate once a month or even less depends on our social life.
At the beginning I didn't mind and I used to fake it so he would just stop and go to sleep but recently I haven't been able to do that. I told him so many times I don't like drunk sex as it emotionless but he thinks it's not a big deal.
I come back from work and I try with him every single day pretty much but he's not interested. However I walked on him few times while he was masterbating but I acted like I didn't notice. I really don't know what to do.
Do you think we need to see counseling?
