Subdrop

What is subdrop?

Subdrop is the emotional and physical crash that can hit the receiving partner after a BDSM session: emptiness, crying spells, irritability, headaches, or exhaustion. It can happen within the hour, but more often it shows up on day two. Subdrop is the submissive version of drop and the counterpart to domdrop.

What subdrop looks like in practice

Rarely in the moment itself. Usually on a Tuesday morning.

Here is how it often goes. The session was good, the evening after is fine, and then two days later you are sitting at your desk and something is off. You are short with people, you cry at a commercial, or you feel like you did something stupid that felt nothing but right at the time. That delay is exactly what makes subdrop hard to spot: by then the connection to Saturday is already gone, and the person you played with is no longer around.

The form varies a lot. Some people mostly get physical complaints, others mostly the sense of emptiness, and others shame about what they asked for. What they share is that a peak came first.

When subdrop is not a BDSM phenomenon

More often than the scene assumes. The dip after a peak has been described outside BDSM too.

Joel Maczkowiack and Robert D. Schweitzer put a questionnaire about postcoital dysphoria to 1,208 men in the Journal of Sex & Marital Therapy: unexplained tears, low mood, or irritability after otherwise satisfying, wanted sex. 41 percent had experienced it at some point, 20.2 percent in the previous four weeks, and 3 to 4 percent regularly. They found links with current mental health problems, with childhood sexual abuse, and with a number of sexual dysfunctions.

That is not a BDSM study, and that is exactly the point. If one in five men experiences this in four weeks of ordinary sex, then a dip after an intense scene is not automatically caused by the scene. It matters for what you do afterward: subdrop does not have to mean something went wrong, and it is no proof that things went right either.

Why the aftercare you get does not always fit

Because that aftercare also does something for the person giving it.

For The Journal of Sex Research, Katie Holstein Mercer spoke with forty people who take the dominant role, about aftercare. What she found is uncomfortable and useful: those people also use aftercare to steer the impression they leave, with their partner, with the wider community, and with themselves. How they understood and described aftercare also varied by gender.

Translate that to the night itself and something practical follows. The blanket, the water, and the question “was that good for you?” come partly from the other person’s need to know they did well. That is not dishonest, but it does make the answer “yes, wonderful” the path of least resistance. And it explains why aftercare almost always happens right afterward, while subdrop most often comes two days later: at the point when there is nothing left to steer.

The word only exists inside the scene, by the way. The Woordenboek der Nederlandsche Taal, the historical dictionary of Dutch, has no entry for subdrop, and the newspaper archive of the Koninklijke Bibliotheek returns zero articles, in either spelling, while aftercare returns 133 and nazorg well over fifty thousand.

What subdrop is not

Not a sign the session went too far. A good scene can leave a dip and a mediocre scene can leave none. The strength of the crash says something about the height of the peak, not about the quality of what happened.

Not something only subs get. The dominant side has its own version, domdrop, and it gets less attention because people ask about it less.

Not something aftercare prevents. Aftercare softens and connects, but there is no evidence at all that enough blankets and water can switch off a dip two days later.

What I see myself

I am Victor. I have worked in BDSM for twenty-five years and have a background as a psychotherapist, and I have learned not to go by what gets said right after it ends.

Almost everyone says on the night itself that they are fine. That is usually true in that moment. The messages that matter come on Monday or Tuesday, and they rarely start with “I have a dip”. They start with a question about something small, or a remark about something else. So I send a message myself on day two rather than waiting for someone to reach out, because the threshold for reporting an empty feeling is higher than the threshold for answering.

What you can do yourself

• Set a reminder for day two, for yourself. Not to check whether you have a dip, but to pause and notice where you are while you still know where it came from.
• Say before the session what you need afterward and when. “I want a message on Tuesday” is a more concrete agreement than “we’ll do aftercare”.
• Ask for something specific instead of waiting for someone to offer. What you get offered is partly shaped by what the other person is used to giving.
• Tell someone if you have a dip, even if the session was good. Staying quiet lets the other person think nothing is needed, and that is exactly what they would like to believe.
• See a doctor if the low mood lasts longer than a few days or keeps coming back. Postcoital dysphoria has been linked to mental health problems, and that deserves better than a blanket.

More on subdrop

• Drop lays out the four forms side by side and covers the timing and the strength of the evidence for the common physiological explanation.
• Aftercare is about the care itself, and what the saliva measurements show about it.
• Mercer’s article is written from the other side, which makes it instructive for anyone choosing the receiving role.

Where this fits on this site

If you have had subdrop after a night with someone else and want to know how it can go more gently, the page on aftercare and subdrop sets out what I do about it in concrete terms, including in the days after. That same care belongs to every BDSM date. Asking a question costs nothing and commits you to nothing.
