WIBTA if I asked my boyfriend to help out more

I live in a small mountain town in a fixer-upper. My boyfriend and I both love to rock climb. He stays with me about 1/3 of the time, with eventual plans to move in. I pay for the mortgage, utilities, everything. He contributes some (groceries, cleaning, random things for the house) as well as helps with some house projects (his idea, to "earn his keep"). I have never asked him to help financially, because I figured I'd be here whether or not he was here. And when he's here, he does spend a lot of his time climbing (understandably)! This means he's usually too tired to help that much around the house/yard, so either I have to do it or pay someone to get it done. (Figure on average he's spending 1-2 hours/day for house projects and around 4-5 hours climbing.) I'm starting to think he should spend as much time helping around the house as he does climbing (e.g., 2-3 hours doing each). But again, my situation would be the same regardless of whether or not he was here. WIBTA for (asking for and) expecting more help? The way my expectations are right now I think I'd be really disappointed if he didn't agree or pull his weight, but I want to make sure I'm being reasonable. TIA!
