Doctors are human and I don't assume what they say is gospel. I've learned that when I was young and called my pediatrician on a misdiagnosis. And he was a terrific doctor.
The medical profession is invaluable, but sometimes, even a routine physical can be like taking your car in for servicing where you know if you don't stand you're ground, you're likely to get screwed (like being put on a prescription you don't really need).
And not every doc is going to be ok with what you're into. Sometimes it's just better to be with another who is more open to things and not judgmental.
We can't know everything, but it is good to learn as much as we can when dealing with "experts" such as doctors. They can't know everything either, and can be judgmental from their own particular vantage points. One doc may assume if there's breast growth it is undesirable to you, and wants to be helpful with that.
May we have the confidence to reply...I really like them, and I'm hoping they'll become even bigger.
