The artist Tom of Finland would just draw his fantasies about men in leather with impossible cocks and bodies. Apparently he was not into black men sexually but he did draw some black men in the 80s since people complained about his drawings not showing black men at all. I know he did find the Nazi uniform to be HOT but he was not a neo nazi or a Nazi sympathizer and those sorts of fantasies about an SS/Nazi uniform are common even among straight people. Just look at the old movie IIlsa She Wolf of the SS. As far as him being hung goes I read that he was average and intact or uncut with a foreskin since he was from Finland where nobody gets cut.
