Absolutely! But as far as we can tell, that's a very old part of our culture. Here's a quote from the wife of a Caledonian chief. “We fulfill the demands of nature in a much better way than do you Roman women; for we consort openly with the best men, whereas you let yourselves be debauched in secret by the vilest” Women were allowed to chose their mates and sex wasn't seen as shameful and to be hidden. Rome, of course, found this abhorrent.
