Dick pictures. I do not like when a man sends them in a first contact email or direct message, EXCEPT when those photos come from someone I know and when those photos are tribute photos. Those are the best!
I welcome those anytime and every time.
I find those photos hot. Why? Because I get off (not sexually, but mentality & emotionally) knowing that a man is wanking off to my photos. I feel sexy & desirable.
My favorite of all of them is the first one below.
