As a guy, I can honestly say it wouldn't be that great. Life is not a Hollywood movie where every girl that walks through the door look like a model. Old women, obese women, women with genital deformities, yeast infections... It's not exactly a porn flick in action, you know?
Actually I have never asked myself that. Most gynecologist are also obstetricians, so half or more of what is walking, or waddling depending on how far along, thru their office door has a belly stretched beyond comprehension, complete with stretch marks that are not for the faint of heart!
