Actor Neil Patrick Harris says he felt humiliated after losing his virginity at a party as the girl left immediately and refused to date him.

The `How I Met Your Mother` fame star opened up about the incident on NPR's show `Fresh Air`, reports contactmusic.com.

Recalling the moment, the actor said: `We were at a party and some girl was there from college with a friend and (she) told my group of friends that she wanted to have sex with me because I was on a TV show.`

`And so my friends were like, 'This is the time! It's perfect! You have to have sex right now!' It seemed perfect at the time ... so it happened.`

"So it was very warm and exciting and it was done very quickly. And then she was done -- she didn't want to date me or anything ... I was sort of shell-shocked by it all. .... I thought, 'OK. Where's my pants?' And then she was gone. It was very unceremonious."

The 41-year-old actor came out as gay in 2006 and is now married to David Burtka.
