Can we ask on law community for the laws about relationships?
As far as I'm concerned, questions about the law that contain words that might be taboo in some cultures - sex, kiss, etc - are allowed, as long as they are on-topic.
Having these in your title might limit its audience (e.g. some words are blacklisted from the Hot Network Questions list).
You might find that you can express your question without these words, but alone, they are not enough to render a post offensive.
