Neil Patrick Harris is photographed by superperv Terry Richardson for the cover of Rolling Stone, so of course the image is sexualized and centers around his penis—sort of. It's a great shot (though that left iris seems oddly large or something?), and NPH is basically gay divinity by now, showing others how one can be an artist and openly gay in Hollywood and have an apparently happy life.
In fact, NPH says coming out helped his career (almost as much as Harold and Kumar Go to White Castle did):
“Once all the cards were on the table, I got more opportunities than ever. Some actors don't get hired because you can't look into their soul and see what they're like, because they're kept guarded.”
