First of all, this is not about (possible) trolling, which is already being dealt with in another question.
It's not always easy to determine the necessary level of detail to be given in a question. Oftentimes, users have to ask for more information, sometimes it seems that there is too much information.
Two (three for nitpickers) questions were posted recently that dealt with sexual intercourse. Both were deleted, so I will quote or paraphrase to enable everyone to participate in the discussion. These two questions varied in the amount of details they gave, so they may be taken to represent both ends of the spectrum.
Question 1: Awkward situation with the director of our lab, due to a hookup after the holiday party
We're both male and gay, and we had consensual, anal intercourse back at his apartment, with me being the receptive partner.
This question has its own discussion on meta.
Question 2: How to say no, during the middle of sex,
This question was more explicit with the OP going more into detail about fellatio and what part of it she doesn't want to perform.
I will quote anongoodnurse's sanitized, but, according to her own admission, a bit broad, version of the problem (source: see link below):
I love my boyfriend, and I like to please him, but he has this thing that he likes and I don't. How do I tell him I don't want to do what turns him on but turns me off?
This question has its own discussion on meta.
As you can see, the problem this question is about affected my question itself.
Now, sexual relationships are certainly on topic, since they contain a lot of possible interpersonal problems. And we should give people with questions about how to handle the IPS aspects of it the opportunity to get helpful advice. After all, the anonymity of the Internet allows us to be more open about it without fearing to lose face in front of the people we know.
Furthermore, this is an international site with users from all over the world. This suggests different sensibilities.
Where do we draw the line between language that's making us uncomfortable (but maybe not others), up to being NSFW, and a level of detail to make a question not too broad? How do we deal with such (explicit) language?
