Serodiscordant simply means one of you has HIV and one of you doesn’t. Some gay couples use the term “magnetic couples” to mean the same thing.
There’s very little research on how successfully serodiscordant, or mixed, couples cope with the complications of HIV.
According to The Body, an online HIV resource guide, “research of this nature tends to measure the most negative aspects of positive/negative couplings, telling us primarily how HIV complicates our lives. It tells us very little about the rewards, the discovery of inner strengths, the emotional ties, the opportunities for developing better communication skills, or the joy generated when a mixed-status couple does create a happy, strong, fulfilling relationship.”
