According to Schumer, the severity of the experience didn't even register to her until she read through old journals, looking for material for her new memoir, The Girl With the Lower Back Tattoo.
"I didn't think about it until I started reading my journal again," the Trainwreck star said. "When it happened, I wrote about it almost like a throwaway. It was like, 'And then I looked down and realized he was inside of me.' He was saying, 'I'm so sorry,' and 'I can't believe I did this.'"
While this isn't the first time Schumer has opened up about losing her virginity, it is the first time she's described the experience as non-consensual. The comedian also mentioned the encounter in last month's Vogue.
"I was always crazy, but I wasn't promiscuous," she told the magazine. "[My friends] were acting out sexually years before me. I loved being around that, but I didn't have sex until I was 17. And I didn't give a blow job until I was well into college."
Though Schumer admits she didn't have many sexual encounters until her college years, losing her virginity wasn't the only time she experienced non-consensual sex. She also told Marie Claire about an instance in which she was "ignored" by an ex-boyfriend when she tried to reject his advances. "I was saying, 'No, stop,' and it was just completely ignored," she said.
While neither of the men are in Schumer's life anymore, the Emmy-nominated actress says she has no desire to punish the man who took her virginity. "This was 17 years ago," she said. "There are just so many factors."
Schumer's sexual experiences have made her more aware of rape culture and victim blaming. "You know, with the rape survivor, it's not just shaming, it's fury," she explained. "It makes people so mad if you're not a perfect victim."
But good relationships aren't lost on Schumer, either. The Inside Amy Schumer star also opened up about her relationship with current boyfriend, Ben Hanisch.
"I feel like Ben is the first guy who's really been my boyfriend. There are guys who, if they heard me say that, would want to punch me in the face, but yeah, it's the truth," she adorably revealed, before adding that being in love is "the scariest thing in the world."
"Every time we say good-bye, I think, 'This will have been a nice last week together.' Or I tell myself nothing is real and he's going to leave me and tell me he never loved me. I feel so bad for him," she revealed. "How exhausting it must be dating me."
Schumer's memoir, The Girl With the Lower Back Tattoo, is set to release on Aug. 16. "People are going to know everything about me," she told ET about her upcoming book, revealing that the memoir will explore her "childhood, big break, family and feminism."
