Actor Neil Patrick Harris has gone nude for the cover of Rolling Stone's latest issue.Harris, 40, who appears on the front page wearing nothing but a bowtie with a top hat placed strategically to cover his private parts, said his sexual orientation as gay contributed to work opportunities he gained, reported Ace Showbiz."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," he said.The How I Met Your Mother star , who is currently playing transsexual German glam rocker in Broadway's Hedwig and the Angry Inch, said he was particular about his image as an actor."I have always been highly aware of how I was presenting myself. Which, now that I'm playing overtly feminine and loving it, is kind of a stupid concern."I didn't think he could pull off the femininity of [the role]," his fiance David Burtka comments on Harris' character. This is such a stretch for him. In his day-to-day, he's not a very feminine guy."
