"Your first time shouldn't be with just anybody. You want to do it with a great guy. It should be with a guy with beautiful — someone who really cares about and understands women. A guy who cares whether you get health insurance, and specifically whether you get birth control. The consequences are huge. You want to do it with a guy who brought the troops out of Iraq," Dunham says.
"You don't want a guy who says, 'Oh, hey, I'm at the library studying, when really he's out not signing the Lilly Ledbetter Act. Or who thinks that gay people should never have beautiful, complicated weddings of the kind that we see on Bravo or TLC all the time," she adds.
Dunham reaches out to young voters in the 60-second spot, telling viewers, "It's also super-uncool to be out and when someone says, 'Did you vote?' and you go 'Nah. I didn't vote, I wasn't ready.'
"My first time voting was amazing. It was this line in the sand. Before I was a girl, now I was a woman. I went to the polling station, pulled back the curtain, I voted for Barack Obama," she says.
The video received harsh criticism from conservatives on social media and was trending on Twitter Thursday with the hashtag #myfirsttime"
"Just so we’re absolutely clear: The ad kinda'-sorta’ [sic] jokingly equates voting for President Obama with losing one’s virginity. No, really," wrote Becket Adams of The Blaze.
"Meanwhile, the federal government has finally topped $16 trillion in debt, millions of Americans are out of work, the Middle East is on fire, the eurozone is in shambles and dependency on food stamps is at an all-time high."
Dunham responded on Twitter Friday to the barrage of comments.

The "Girls" star also recently contributed to a politically themed reenactment of singer Lesley Gore's 1960s song "You Don’t Own Me." The video, which has gained some traction since its release earlier this week, also included Gore herself, actress Natasha Lyonne and model Alexa Chung singing along to the female-friendly hit.
