I feel like the man

Hey y’all! I am 30 years old in a relationship with a 39 year old and I feel like the man as in wanting sex from him. We have sex like once a week or every other week and it drives me crazy. He says we can’t do it on week days cuz he has to get up for work. Fridays and Saturdays he hangs out and comes home drunk can’t do nothing then. And on Sunday well Monday is a work day. I’m sexually frustrated and don’t know what to do. Other than his lack of sex and romance he’s a great guy. Mostly every time we have sex I have to initiate and some times I initiate and get rejected. I’m so lost on what to do God knows I don’t want to get piped down outside the house but it’s hard sleeping next to him and feel like I gotta beg for it.
