How often should a married couple in their early 40s have sex per week to be considered as having a healthy sex drive?

Not written in stone: Amount of "sex drive" is not the only thing affecting how often a couple has sex. Both may have a healthy sex drive, yet relationship conflict may make them not desire sex with each other. Frequency of sexual intimacy (and satisfaction with this) varies widely. One study suggested that 40 to 49 olds have intercourse an average of 69 times a year. For more info: http://tinyurl.Com/mxnfhc3.
