Ok guys, let's break down the difference between reality and fiction, as well as turn ons and offs. As a general rule, in reality, many women find contact with their cervix very painful. Women who have IUDs inserted (through the cervix into the womb) usually relate that they experience a lot of pain either on insertion or in the days following. And that's a tiny medical device. In reality this act is Just about impossible... but so are alien tentacles and those predate all modern hentai. I think this tag is important to use as it can be either a massive turn off (for people who prefer realistic anatomy) or a massive turn on (for people invested in the fantasy).

Oh you silly little boy @Basil_Ocimum, of course it's going to hella hurt a lot irl, this is best done by 'pros' that are used to it like those nearly impossible poses done by contortionists. But enough of real life examples, the only thing that matters at the moment is the tag description. I already posted my version, does anyone else have better ones?

no it really isn't possible man, if you somehow get pass the hole it isn't going to be "pleasure" it's going to be a fuckin' hospital trip, don't get your SexEd on porn it's really shit

I don't know about that "started by virgins" bit but 'impossible'? There are live videos of women prolapsing their uteri, dilating their cervix and then proceeding to diddling the gaping hole with sizable toys so I think it is possible (no way I'm jumping into that giant rabbit hole any further, no pun intended). About that description, does it also include other foreign objects beside the penis? A bit of clarification wouldn't hurt. "The cervix/womb of a female is visibly penetrated, usually by a penis." This will add the insinuation that other foreign objects like tentacles are included, as reflected by some tentacle doujins that have that tag.

This is also biologically impossible btw and started by virgins

My reaction when she say "deeper!".
