Penothologist 

A doctor who specializes in the penis in a sexual way only. It is unlike a urologist whose focus of the penis is cold and clinical. Also used when trying to name a doctor who works with the penis and you can't remember that they are called urologists.

Honey I am noticing that my penis is swelling when you are in that sexy outfit. If this persists I might need to see a penothologist !!
