Couples' frequency of sexual activity varies greatly and is impacted by a broad range of variables, such as personal preferences, health, age, relationship dynamics, and outside pressures. The frequency of sex between "normal" couples varies widely from couple to couple, so there's no one-size-fits-all solution. Furthermore, as a relationship progresses, expectations and aspirations often shift.

An overall knowledge of couples' sexual frequency has been tried to be provided by a number of research. A 2015 research that appeared in the journal "Social Psychological and Personality Science" found that American couples engaged in sexual activity on average once a week. It's important to remember that this is an average and that every couple will have a different idea of what constitutes normal and satisfactory.

Individuals vary in their libido, or amount of sexual desire. Some people may be OK with less regular sexual activity, while others may have a stronger desire.Over the course of a relationship, sexual frequency often varies. It could change as the relationship gets older and become more regular in the beginning.
