This article, My Husband and I Had Sex Every Day for a Year — Here's How We're Doing Now claims that a particular married couple have had sex (almost) every day for a year.

I am skeptical - Are most men physically capably of having full sex (including ejaculation) 365 days in row?

This is a physical/medical question and is not aimed at asking any of the related interesting questions about sex.

  • Most comments were speculation.

  • I’m not a frequenter of the Skeptics site, but I don’t understand why this question has been downvoted so many times. I’m not necessarily objecting, but I’d still like to know why. Jan 11, 2018 at 15:31

    @ChaseRyanTaylor Probably a lot of men know for themselves that it is easily possible, so they think it is a silly question. But then there are other people, like young women/girls, that have no way of knowing, or men/boys who never been in the situation of having sex with a partner many days consecutively, who upvote.

  • @ChaseRyanTaylor: This question is (now) structured like a valid Skeptics.SE question and follows all the community standards, so I am leaving my mod hammer in its holster. However, typical questions start with an extraordinary claim - the skeptical stance is to ask for evidence before accepting it. This starts with a rather prosaic claim, and it requires an extraordinary speculation to doubt it - that there is a hypothetical limit to sexual acts that is unlikely to be met.

1 Answer 1


The biological limitation on men having repeated sex is called the Refractory Period. During this period, after orgasm, a man is generally unable to maintain an erection or achieve orgasm, and may be psychologically uninterested in sex.

The refractory period varies between men and increases with age. For younger men the period can be a matter of minutes. For older men it can be 12-24 hours. In some cases it can be days. There is also a refractory period for women, but it is more complex and in any case does not prevent a women physically from having sex.

Without an experiment there is no way we can be certain it is possible, but we know of nothing biological preventing some (probably most) men from having sex every day.

    I am not sure about the scientific basis for this answer. Take a young man with refractory period of 20 minutes. I don’t believe he could have sex and ejaculate 72 times in a 24 hour period. There is a cumulative effect that is not covered by the refractory period.

    I agree with @felipa I don't think this answer shows any evidence that the refractory period is the only limit to having sex. There's likely some sort of cumulative effect.

    My point can be extended to sex every day. The fact that you can have sex three days in a row doesn't mean you can have it 365 days in a row necessarily.

    This answer is theoretical: theoretically if one has a refractory period of less than 24 hours, they could have sex every day; practically you haven't shown that they can do so 365 times in a row. I'm leaving it because it does acknowledge some of its limits, but that makes it a very partial answer.

    @felipa - well, just because your friends didn't, doesn't mean they couldn't. I had a couple relationships where at least daily, for a fortnight or more, was not an issue, so if we're going by anecdote, there's that. Remember, you're not asking if everyone or even most people can, you're asking if it's possible. Jan 4, 2018 at 16:17
