Frequency of sex…married couples?

I’ve asked this question in a subreddit that pertained to questions regarding sex, but was curious if the responses may differ here, beings that since it was a subreddit pertaining to sex, I’m sure the people there are there for sex type topics and may by chance have more sex. That definitely is not to mean that all people may not like or enjoy sex, I’m just wondering if responses there may be slightly skewed. I mean they could be anyways with people not answering truthfully though.
