Yes, I think some people would be very comfortable with this.
As a matter of fact, I know people whom I have worked with who have been married several years and do you know what? They are only intimate once a month! They set a date for that. I have heard of others where it is only once a year.
Might sound dreadful to some but to these people, they don't mind at all.
