Apparently it is close to impossible to see, let along catch on tape, two hedgehogs having sex. But last week a man in Leikanger, Norway came home to find two of them go at it on his freshly mowed lawn.
Having sex with another hedgehog is supposed to be painful but the man said the male did not seem to mind (though he did have to take a few breaks), while the female seemed to experience some discomfort.
There is a saying which seems very appropriate in this case...
"Etter den søte kløe kommer den sure svie."
...which I'm not sure exists in English (at least I haven't been able to find it), but would be something like "after the sweet itch comes the nasty burning [sensation]".
Something like that (I suck at translating), but it seemed to fit for two hedgehogs going at it.
