The Italian word for sex is sesso, and the act of making love can, like in most languages, be described in a number of ways; from the phrase 'fare l'amore' (to make love), through to the more scientific copulare, and in a number of more explicit ways...
Sex plays an important part in Italian society and the attitude Italians have to sex, collectively, can be markedly different from the approach of other countries.
In fact, Italy makes an interesting study in sexuality as it is somewhat of a fault line; the liberal, hot-blooded Italy portrayed by scantily clad TV show hosts and the infamous Italian 'playboy' lifestyle being just as relevant as Italy's more conservative, family-orientated and Catholic heritage.
One interesting publication in the field is the book 'La sessualità degli Italiani' by Marzio Barbagli, Giampiero Dalla Zuanna, and Franco Garelli, in which they explore the ever-developing role of sexuality in Italian culture.
