Rachel says they're also turned on by the idea of “sharing” her, which means that occasionally, they'll all have sex at the same time.īefore she met her boyfriends, Rachel had had a few threesomes with other women. They both know each other, and they're cool with Rachel having sex with each of them individually. Rachel is polyamorous, which means she is in relationships with multiple partners - in this case, two men. 'It's one of the best parts,' she gushes. What makes it an Eiffel Tower is when the two men high-five each other, forming the point of what is basically a squirmy, sloppy triangle. To be clear, Rachel isn't referring to the iconic Parisian landmark: she's referring to a slang term for a sex position where a woman is on all fours and giving oral sex to one man, while another man has sex with her from behind. “The Eiffel Tower is such a thing,” says Rachel* (names have been changed to protect sources' privacy), a 25-year-old recent college graduate.
