Lena Dunham, creator of hit HBO show ‘Girls’ says she won’t marry her boyfriend until her lesbian sister is allowed to legally marry too.

During an interview with Howard Stern, the 28 year-old said that she will not marry boyfriend Jack Antonoff until her younger sister Grace (22) can marry as well. She told Stern that she considers Antonoff, guitarist in rock band Fun., her “life partner” but will still wait to tie the knot.

“We’re not against marriage, but I want to wait until it’s something … my sister’s gay and it just doesn’t feel good to me to do something she can’t do. She can do it in some places but not all places,” she said.

Grace came out while she was in high school, and Dunham credits her with giving her a better understanding of the LGBT community. While accepting an award from the Point Foundation, an LGBT scholarship fund, Dunham said,” I have always felt a strong and emotional connection to members of the community. It was actually a huge disappointment for me when I came of age and realised that I was sexually attracted to men.

“So when my sister came out, I thought, ‘Thank God, now someone in this family can truly represent my beliefs and passions.'”

“We were raised in an environment where no one hid their sexual orientation, and a common question from 4 year-old me was ‘Mum, are those ladies gay together?’”

“My sister’s process of coming to terms with her sexuality was as angst-free as anything involving sex can really be. She was assured by the adults in her life that she was not only accepted, but adored for who she is.”
