What is ‘Slutty Pumping’?
TikTok’s ‘NSFW Hack’ for Boosting Breast Milk Production: What’s the Deal with ‘Slutty Pumping’?
In the ever-evolving landscape of parenting hacks on TikTok, a particularly eyebrow-raising trend has caught the attention of curious (and exhausted) new parents everywhere. Dubbed “slutty pumping,” this NSFW-named practice involves pumping breast milk immediately after intimacy—with some TikTok users swearing it leads to a noticeable increase in milk supply.
Yes, you read that right. It’s sex… then pump.
So what’s going on here? Is this yet another quirky TikTok myth, or is there actual science behind it? Let’s break it down.
Where Did ‘Slutty Pumping’ Come From?
The trend seems to have gained traction after a few TikTok creators—mostly breastfeeding moms—shared their surprise at producing more milk when they pumped after intimacy. Videos using hashtags like #sluttypumping or #milkbooster have racked up millions of views, with users citing hormonal surges and oxytocin spikes as possible reasons.
“Every time I pump after getting it on with my partner, I get so much more milk,” one mom shared in a now-viral video. “I’m not saying it’s science… but I’m also not not saying that.”
Cue the flood of comments, from intrigued parents trying it out to lactation consultants weighing in.
What the Experts Say
Turns out, there might be something to this.
Dr. Jessica Madden, a board-certified pediatrician and neonatologist, explains: “During sexual activity and orgasm, the body releases oxytocin—the same hormone that triggers the milk ejection reflex during breastfeeding.”
In short: your body doesn’t totally differentiate between sexual intimacy and feeding your baby when it comes to hormone release. Oxytocin, also lovingly known as the “love hormone,” plays a role in both.
“So, theoretically, pumping after sex could help some people let down more easily or more fully, which might result in temporarily higher milk output,” Madden adds.
However, she cautions that this doesn’t mean it’ll work for everyone—or that it will boost long-term milk supply.
Anecdotes Aren’t Evidence—But They’re Not Useless Either
While there’s no peer-reviewed research specifically on “slutty pumping” (yet), the connection between oxytocin and lactation is well-documented. Still, experts stress that everyone’s body responds differently.
“There’s a huge range in how lactating parents experience letdown,” says certified lactation consultant Hannah Reardon. “For some, emotional or physical intimacy can make it easier. For others, stress—even if it’s ‘good’ stress—can do the opposite.”
In other words: don’t feel like you have to try this to be a successful breastfeeding parent.
Practical (and Emotional) Considerations
Let’s get real for a second—postpartum intimacy can already feel complicated. Trying to turn it into a milk-maximizing strategy might not be realistic (or appealing) for everyone.
“If it works for you and feels good, great,” says Reardon. “But please don’t pressure yourself into performing intimacy as a productivity hack.”
Also worth noting: if pumping after sex does help you produce more, make sure you’re storing milk safely and keeping an eye on overall supply patterns, not just the output from one session.
The Bottom Line
TikTok’s “slutty pumping” trend might have a scandalous name, but at its core is a conversation about how intimacy and breastfeeding intersect—something rarely talked about openly. While the science behind it makes sense hormonally, this isn’t a one-size-fits-all fix for milk production challenges.
If it intrigues you and you feel comfortable giving it a shot, go for it. But if it’s not your vibe, that’s totally okay, too. As always, when in doubt, talk to a lactation consultant or your healthcare provider about your breastfeeding journey.
And remember: no matter what TikTok says, your worth as a parent is not measured in ounces.
