Can I tell the man I'm dating on our first date what my expectations are for the entire relationship?
Why do you want to discuss those expectations on the first date?
I want to make sure he clearly understands what I want and expect from a romantic partner.
I know that you want to be clear and state your needs and expectations, but that could make you appear like you're coming on too strong. If you're seen as demanding it might make him have second thoughts. Be patient and see how the relationship unfolds first before making too many demands.
I don't really care what he thinks..
If you don't care what he thinks, then why even date him? It sounds like this whole thing is off to a bad start, and you shouldn't put too much on the plate after one date or else he may run off.
