I'm hayriding with a future proctologist. I have potential.

我要和一个未来的直肠科医师一起出游 我有(结婚的)潜力。

Let me ask you, would I see a podiatrist or a proctologist...

请问，我能找个看腿或者直肠的吗？

But if you really don't want to do that, a proctologist has to do with things related to your butt – to that part of the body that you sit on.

但如果你真的不想那样做，直肠科医生必须处理与你的屁股相关的事情——与你坐在上面的身体部位有关。
