Male condom and dual protection use by adolescent men in Brazil.

The wide difference shown in the proportion of condom or dual protection use in the last sexual intercourse draws attention to the different logics that govern juvenile sexual relations. The low proportion of dual protection use may be a reflection of men's lack of knowledge about a function that has historically been attributed to women, which is contraception. Thus, one must deconstruct such dichotomy that the sphere of sexuality is of the domain/interest of men, while that of reproduction concerns only women.
