Welcome to NSFW Sunday!

+ Dating apps can feel addictive:
“‘Dating apps are basically slot machines—there’s the promise that you’re going to find something good, and every once in a while you get a little positive reinforcement to keep going,’ says David Greenfield, founder of the Center for Internet and Technology Addiction and a professor of psychiatry at the University of Connecticut School of Medicine. Researchers call it variable ratio reinforcement: The prize is unpredictable in terms of how much, or when, but it’s out there. And as we swipe for a mate—or sex—enough attractive matches and promising texts provide that mini-hit of dopamine to the brain that keeps us coming back for more.”

+ Why are people into watersports? At the Establishment, Cyd St Vincent, Princess Kali, Nikki Darling and Matthew Lawrence discuss sex work, golden showers, kink, the obvious news-related association here that I am not typing out on purpose and more. Princess Kali says:
“Golden showers and playing with other bodily fluids for sexual purposes are often about confronting taboo. But really, like all kink, it’s a very personal experience and the emotional headspace that happens during piss play isn’t always what’s expected. Piss play is probably most often used in erotic humiliation scenes, as a way of lowering the status of the ‘human toilet.’ But I’ve also known kinksters who enjoyed peeing on each other as a sensual and intimate expression with no humiliation involved at all. If we didn’t have social mores around urination, it wouldn’t be such a powerful taboo to play with.”

+ Here’s what it’s like to be queer and come out as a stripper.
+ Blood tests for herpes can often be wrong, so make sure to talk over whatever result you get with your doctor. And if it turns out it’s a true positive, here’s how a hostage negotiator recommends sharing the news with sexual partners; open with “I have some bad news” and say what’s up immediately, don’t use euphemisms, remember it is your fault, and remember they’re entitled to feel angry or annoyed.
+ If you’re kinky, you’re probably not out to your healthcare providers, and you probably wish you were.
+ Still looking for a gift for yourself or someone else for Valentine’s Day? Check out our color-coded sex toy gift guide, which is probably my opus. Or, stay tuned for Crash Pad Series’s Valentine’s Day sale, which will include 15% off on memberships (check its social media for the coupon).
+ At Oh Joy Sex Toy, Erika Moen writes about squirting, noting, “ejaculation is something that almost every body can do! It just works and looks a bit differently depending on which set of junk you have.”
+ Ejaculating dildos: fun as an IVF alternative, fun for play.
+ Sincere compliments are like if your brain is having very tiny sex.

+ Your brain processes sex, drugs and your favorite songs in the same way, according to new research that focuses on music and the opioid system:
“Subjects put on headphones and researchers measured their involuntary movements. The subjects also controlled a sliding scale with which they reported how engrossed they felt in the song from moment to moment. The scale went from 0 to 100—0 presumably representing how one absorbs the soft jazz played at Panera Bread and 100 an experience on par with popping a Queen cassette into the deck of the Mirthmobile.
Although they didn’t know when they were on [opioid-blocker] naltrexone, respondents were much less into the songs while they were. The study concluded that ‘music uses the same reward pathways as food, drug and sexual pleasure.’”
