This is hard to say because each couple is so different. Some couples do best when they have sex daily. Other couples prefer weekly or every other week. There are even couples that prefer to not have sex at all.
Resident sex therapist Dr. Kyle Zrenchik recommends couples to have sex no less than 1-2 times every 1-2 weeks to ensure that they are experiencing enough sexual intimacy.
Sexual intimacy, as Dr. Zrenchik states, is more than just sexual frequency. “It involves sharing emotions, being vulnerable, and taking risks. Also, it involves experiencing something inside the bedroom that is different and special.
Sexual intimacy provides a vehicle for connection and relationship building that cannot be replicated in any other way.
Both emotional and sexual intimacy are crucial factors that affect a couples overall relationship quality.
Ultimately, it is up to the couple to determine their ideal sexual frequency. As long as the couple feels sexually connected and satisfied, then the number is largely irrelevant.
