It's like the time the EMH popped up on a monitor while B'Elanna was dressing (can't remember episode). She tries to cover herself, but he rather smugly says it's nothing he hasn't seen before. Wouldn't surprise me if he's as lecherous as Barclay on holodecks.
He's the only gynecologist (and urologist) aboard, for over 7 years. He has seen and touched everyone's everything.
