If I could put my two cents in, I'd like to point out the fact that, in one of the pictures, he has a cigarette box beside his (admittedly impressive) soft member. Now, correct me if I'm wrong, but if someone puts a cigarette box beside their cock as a pseudo-measuring "stick" and that very picture gets on the INTERNET, how can you even begin to claim that his privacy is infringed? For one, somebody with that kind of inclination is more likely than not an exhibitionist, and secondly, if he regretted taking the picture after the fact, he would have stopped their appearance on the INTERNET. I've never heard anybody complaining of Brad Pitt's infamous nude shots, and it can clearly be seen that those were taken with a zoom lens. This, on the other hand, is clearly free choice--nobody forced him to do what he did.
If anything, I think it would be flattering for Curtis to have so many people "fawn" over his cock.
I, however, might be very wrong.
