I happened upon the website TheMarriageBed.
Here is some of the data that they provided on the subject matter:. About one in six is masturbating no more than once a month.
Based on the notes, a lot of this is men who only masturbate when they are away from their wife. Half of the men are masturbating every 5 to 15 days; this is a moderate amount.
As above, some of this is due to temporarily being away from their wife. Married men that masturbate men masturbate as often as they would be having sex if they were with their wife.
One man in six is masturbating every 2 to 4 days; this is what is normal for a young single man with no other sexual outlet.
This is fairly high, and this level of masturbation is often but not always driven by porn use. One man in 20 is masturbating six or seven times a week.
This may be a habit left from before marriage. One man in forty is masturbating more than daily.
This could be anything from eight times a week to several times a day. See our article on Chronic Masturbation.
Only thirteen percent of wives are aware of how often their husband is doing it himself. This includes a good many who said their wife suggested or Married men that masturbate it when the couple was apart, or during a period of time when she was unable to meet his sexual needs. About half of the wives are aware their man masturbates, but think it happens less often than it does.
Forty five percent of husbands are aware she masturbates, but think it happens less often than it does. When I masturbated, I always likened it to eating a cracker while fasting.
