Narcissexual 

A person who only gets aroused or stays turned on while looking in the mirror.

I was with this narcissexual guy last night who could only have sex if he could watch himself in the mirror.

Narcissexual 

Being sexually attracted to yourself.

"Check out that girl over there. You should try to get her number."
"Bro I've told you before, I'm narcissexual- I'm only attracted to myself."
