Natasha Rose Chenier made the startling revelation on her blog , to raise awareness of GSA (genetic sexual attraction').
Headlining her story 'Falling in and out of love with my dad', the now 24-year-old wrote:
"My biological father wanted to have sex with me from the first moment he laid eyes on me.
"This I learned two years after meeting him, as I dry heaved over his toilet in a moment of all-consuming anxiety and self-loathing. This was just after the second time we had oral sex."
Explaining that she first met her estranged father aged 19, when she visited him in Jamaica from her home country of Canada, Natasha had no idea of what a 'normal father-daughter' relationship was.
Over the two years that she visited him, their relationship grew more intimate, with Natasha revealing:
"We held each other and I felt safe. When I started feeling sexually attracted to him—as well as shocked and horrified to realize it—I spoke of it to no one."
Speaking of her final visit, she remembers:
"We had oral sex a few times, almost always preceded by my descending into a whirlwind of self-hate and disgust and dry heaving over the toilet in the bathroom attached to his room.
"He lay on his bed looking aloof during these episodes, spouting empty reassurances like 'You'll be fine'."
Shockingly, when Natasha gathered the courage to tell a family member, she was accused of 'trying to make her mother jealous'.
However, after counseling, Natasha has made peace with the situation, explaining:
"Genetic sexual attraction is normal, and very real.
"If it is a parent-child relationship, the parent, whether male or female, is always responsible for establishing and maintaining boundaries.
"Failing that, they are sexual abusers.
"I have finally been able to understand myself: that my attraction, and what it led to, was not my fault."
