It seems apropos, somehow, of current pop-culture attitudes thatThe 40 Year-Old Virgin, hyped as a raunchy R-rated alternative to PG-13 comedies, would have such a love/hate relationship with explicit material. On the one hand, it indulges a penchant for dialogue that’s occasionally vulgar (shit-stained balls indeed) and consistently profane (check out the string of swears ad-libbed by star and co-writer Steve Carell in his big did-my-own-stunts chest-waxing scene). On the other hand, its characters eventually evince a weird primness where actual visual depictions of sexuality are concerned. What’s that about?
