The first one drives my crotch nuts, so....

I'd rank them 1 > 3 > 2, and they all get an A+. I love the variation of angles and poses in your pictures--keeps things interesting and fulfills different desires. I prefer men fully nude, but sometimes find the open fly shots hot 'cause it's like peeking at the urinals or something.
You know what could be hot is seeing you around your house completely nude, possibly w/ erection, just doing various activities like pouring some wine or vacuuming. It'll give a new meaning to the Martha Stewart collection, LOL!
