I've Lost The Desire To Please My Girlfriend Down There

I have a difficult time between my professional work and my love life. I am an obstetrics nurse. It is so hard to get in the mood with my girlfriend after a day in the office with pregnant women. If I examined penises it would be something, but I examine pelvic regions on women all day long. I have lost the sexual attraction of a woman's pubic area. I just can't go down anymore.

In my lost moments when I can't sleep I wonder what a penis would do for me. I'm also having pregnant dreams. My girlfriend sound asleep beside me.
