Switching doctors for what?

Everytime I have an appointment, my main doctor is off. And I suggested they schedule me on her days, but the don't! And they literally stick they're finger in me each appointment. I don't even like when my boyfriend does that, it just doesn't go there. But that's besides the point. I feel like the whole nurses team has run threw me. One nurse even said, "I'm just gonna check myself because I don't like to go off of anyone else's measurements." What kind've bull. We wouldn't have this problem if I had the same nurse each time.
