What I think is lame is when the activities of two consenting adults who are acting in a mature and responsible way become juicy gossip for others, possibly because they don't have enough interesting stuff going on in their own lives. I'm not talking about abuses of power or anything like that.
I'm sure you know that people in med school/the hospital sometimes regress into a high school type mentality about things they should be mature enough to deal with in a better way. I don't think it's cool. I'm definitely more of the "what people do in their own home is their own business" mindset.
Again, I am not talking about sex for grades; just "normal" relationships---I know they may not always be totally based in equality, but that's true anywhere in life, not just the hospital.
