How many tattoos is to many for a guy? Where is it sexy for a guy to have a tattoo?

I have seen many guys with several tattoos on there bodies and i don't know if it works for them. I will have 4 tattoos come April 20. I have a skull on my shoulder, a clown on my left forearm, praying hands on my chest and my next one is going on my right calf. I plan on getting several more. I don't know if i want to cover my whole body but i would like to strategically place tattoos on my body not cluttering one part of my body.
