A lot of people probably wouldn't take kindly to their other half divulging all about their sex life - especially with strangers on the internet.
But one couple has done just that, and has piqued the curiosity of thousands of people.
So what makes their sex life so extraordinary that people need to know? Surely, in this day and age, most have us have seen and heard it all before?
In the case of NurseryRN and twicethefunn (their Reddit aliases), their sex life is a little different to most other people's.
NurseryRN was born with a "complete uterine didelphys", a condition wherein a woman has a double uterus, with two cervixes and in the case of NurseryRN - two vaginas.
And after her hugely popular Reddit 'Ask Me Anything', her boyfriend has stepped in to give his no-holds-barred perspective.
Although it seems twicethefunn (we see what he did there) opened himself up to a lot of explicit chat and questioning, many users were genuinely curious and raised some interesting questions.
So what were his first thoughts when he found out?
As for how he found out, the man in question explained:
"Well, before we started dating she mentioned she had two of something most girls don't.After a couple minutes of guessing I finally figured it out. It was an interesting conversation."
Then the questions got a little more anatomical, with one user asking "Does it (sex) feel different?" to which twicethefunn answered:
"Yes, but then again all vaginas are different."
One thing he did point out was other people's confusion over the female anatomy, helpfully clarifying:
"Urine comes out of the urethra, not the vaginal canal. The urethra is near the top of the vagina while the vaginal canal is at the bottom."
Other users asked twicethefunn for details about his own private parts (no, he doesn't have two penises) and with some lines of questioning getting a bit abstract.
As for conceiving and carrying a child, he revealed while his girlfriend could get pregnant via both vaginas, "She knows way more about this than me. Don't ask me how that works though."
Aside from most of Reddit, twicethefunn has also told his close friends about his girlfriend's uterine didelphys.
It seems the decision to go public with their sex life was one both parties in the couple felt comfortable with.
