Hey boyfriend's Reddit username is "twicethefunn," if that gives you any idea …

Last year, YouTube beauty tutorial starlet Cassandra Bankson discovered she was well endowed. After years of excruciating kidney pain, a medical examination revealed she had not one, but two whole vaginas, a revelation she generously shared with her audience.

But while Cassandra is probably the most well-known owner of a double vagina, plenty of other women share her condition (0.1-0.5 percent of American women).

Reddit user NurseryRN was also born with uterine didelphys, meaning she has two uteri, two cervices, and two vaginas. And, like Cassandra, she was generous enough to share what living with two vaginas was like. On a recent Reddit AMA, she answered some very straightforward questions about how sex and reproduction work when you're working with twice the fun.

First off, she busted the physiological confusion with this entirely NSFW picture.

NurseryRN described the anatomy depicted in the photo, which is basically two vaginas divided by a “septum.”

“I’ve been told I can get pregnant in either uterus,” NurseryRN wrote on Reddit.

However, despite working with the extra equipment, she's actually pretty satisfied with her sex life:

"My sex life is good," she wrote. "It depends which vagina is penetrated. My vaginas are side by side and the left side hurts when penetrated because it is smaller. To my knowledge, due to the septum in my vagina, my g-spot is covered. Other than that, I imagine that it’s not much different than anyone else’s … We aim for the right vagina."

However, the septum does limit sensitivity.

"To my knowledge, my g-spot is covered by the septum so I can only have clitoral orgasms and cervical orgasms that I know of," she said in response to a question about whether or not she can orgasm.

One Reddit user had another really good question: is it possible to get pregnant in both uteri at the same time?

NurseryRN answered that although it's rare, it happens.

"Due to hormones, that isn’t supposed to happen but I’ve read that it’s happened before. Apparently a woman had one in one uterus and twins in the other uterus," she said.

However, although she's as fertile as anyone else, nature has enacted some biological mercy by only giving her one period each month. This is because although she has two uteri, they're connected by the same two Fallopian tubes. Hooray!

NurseryRN’s boyfriend “twicethefunn” also got in on the action, starting his own AMA to field questions on what it’s like to have sex with a woman with two vaginas … although his user name pretty much clears that up.

People didn’t hold back and went straight for the juice:

Ha! That last one though.

Anyway, it sounds like having two vaginas is just like having one vagina, except there's two of them. But even though it's less remarkable than it has the sci-fi-esque potential to be, NurseryRN's and twicethefunn's Reddit AMAs are both still pretty fascinating, funny reads.
