The person in the photo has a name, Spencer Elden and appearing on the cover has had a lasting impact on his life. This quote from Wikipedia gives some insight into his conflicts:
For the album's 10th, 17th and 25th anniversaries, Elden recreated the front cover shot for photographers. He wanted to do the 25th anniversary shoot nude but the photographer preferred that he wore swim shorts.[47] In 2003 he appeared on the cover of cEvin Key's album The Dragon Experience.[48] In a January 2015 interview with The Guardian, Elden said "I might have one of the most famous penises in the music industry, but no one would ever know that to look at me. Sooner or later, I want to create a print of a real-deal re-enactment shot, completely naked. Why not? I think it would be fun."[49] He told Time magazine in the following year "[When] I go to a baseball game and think about it: ‘Man, everybody at this baseball game has probably seen my little baby penis,’ I feel like I got part of my human rights revoked".
