The devil in us

He has other names. Such as greed and anger.

My devil is sexy AF

Mine is jealousy

This may be a bit random but I love the song "Demons" by Imagine Dragons. "No matter how we breed we're all still made of greed." I'm not even religious .

I'm a little worried about how big my Satan is

Don't tell this Sam!

Well damn my satan is one sexy guy. He is way sexier than everyone else's devils, obviously.

If you're speaking psychologically, Devil would actually be Id. You as the conscious being are Ego. Then there is the Angel you have named Superego.
