Dear Sarah,
How much sex is suitable and how often should I be having sex?
Dear anonymous,
The easiest way to answer this to say that what constitutes "enough" is what works for your particular relationship.
Definitely, quantity is not the only thing to take into consideration. Like many things in life, it's not the quantity, but the quality of sex that counts.
However, if he or she wants sex every day and you want it once a week, you should negotiate and reach a compromise that includes masturbation, foreplay, oral sex, and intercourse.
