Lena Dunham was ''disappointed'' to discover she wasn't gay.

The 'Girls' star claims her ''connection'' to the lesbian, gay, bisexual and transgender (LGBT) community is so ''strong'' that she was overjoyed when her sister, Grace, 22, came out at the age of 17.

Speaking at Point Honors Gala in New York, which helps LGBT students and those who are questioning their sexuality, Lena said: ''I have always felt a strong and emotional connection to members of the LGBTQ 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'. ''

Lena - who is in a relationship with Fun. guitarist Jack Antonoff - finds gay men attractive, and joked that she had dated a couple in the past.

She laughed: ''This is probably the most attractive room I have yet to enter, Gay men clean up real good, which is probably why I have dated so many of you.''

Lena has spoken openly before of her past relationships with men who have later come out as homosexual, and she insists it's not something she feels ashamed of.

She previously said: ''It's something I'm actually proud of. The best option is that people who are confused about their sexuality feel really comfortable with me. The worst option is that I turn them.''
