For example, I was available for the first two dates. Should I turn down the third date and reschedule with him?

If you already had other plans, you should not drop your other plans just because a guy says he wants to hang with you. You should inform him that you have other plans. However, if the other plans came after you made plans with the guy, it would be rude to change those plans after the fact.
(One exception might be, "Hey my friend from out of town, that I have not seen in years, just called and said that she is going to be passing through on that night. Would you mind rescheduling so that I can see her while she is here?")
Short answer, no. You should not always be available, but you should be honest about your availability. Even if saying no is just because you don't want to say yes. That is your right as a person. If he can't handle it, you don't need him.

If you're busy or have other plans, then it's fine to reschedule. He should respect that your life includes more than just him. You aren't ditching him; you're asking to reschedule.
