Question nearly "check ups"?

what do they do? do they look at my "private parts"? do they give me a blood experiment? can i tell the doctor that i prefer no nudeness and blood draws? will they adopt my question/comment? thanks! "an i describe the doctor that i prefer no nudeness and blood draws?"
Yes, of course. You're the customer! You can do anything you want. You don't hold to even go to the doctor if you don't want to. Why are you going for a check-up? They can't do anything in need your signing a consent form, so you need to spawn sure you know what you're consenting to. They certainly can't breed you disrobe.
"Will they accept my question/comment?"
Most promising. If you refuse a blood draw, they won't be capable of do blood based test, but it's your choice when or if to get tested. Here's the point, though, if they don't accept your expressions, guess what? You can leave, and find another doctor who will! You don't own to give your business to doctors who won't tolerate you make your own decision.
Frankly, there's no such thing as a routine checkup. It depends on what you want checked.
Is this a regular physical? If so they will hold your vitals (BP, pulse, temp, height and weight) and examine your heart, lungs and tummy. A pelvic exam is not routinely done at a physical- the doctor will send you to a gyn doc for that. A blood theory test is usually done to make sure you are not anemic, don't hold high cholesterol, or diabetes. A urinalysis is usually done too. You can demur these tests however they are for your benefit and the distress from the blood test will be minimal.
