Which of the following is NOT one of the steps that intimate couples must negotiate through in order to use contraception effectively?

A) Define themselves as sexually active.
B) Agree on the religious implications of contraception.
C) Have accurate knowledge of fertility and conception.
D) Have access to their chosen method of contraception.

While couples may need to discuss their religious beliefs in relation to contraception, they do not necessarily need to agree on the implications. It is important, however, for couples to have accurate knowledge of fertility and conception, access to their chosen method of contraception, and to define themselves as sexually active in order to effectively use contraception.
