I believe I'm right in saying that English is pretty much the only language in which swearing is dominated by sexual and scatological imagery. Almost all continental languages' oaths are religioncentric...they find our obsession with sexuality/bodily functions baffling. Why would you root your most toxic terminology in pleasurable activities?
Mrs Dr B taught me some Urdu swearwords, which are based on Muslim religious taboos. No surprises that "dog" and "pig" appear, but my favourite translates approximately as "bad meat!".
When we're at my inlaws, my FIL will usually have a Bollywood film on at volume 11. It's a rule that in every Bollywood film there's a point where someone calls somebody else "you bastard!" in English.
