The promo blurb on Go3Fun’s homepage confused me for a second this morning. They call it “The Leading Dating App For Sexually-Free Singles and Partners to Meet Like-Minded People.” At first, I misread “sexually free” as a reference to asexuals. After rubbing my eyes and adjusting my boner, I realized they meant the exact opposite—this app is for adults who are very much interested in sex.
If you’ve got a pulse, a libido, and a sense of adventure, you’re probably the target audience. Go3Fun.co is Home to 3Fun, a dating app designed for adults looking to explore threesomes. The concept intrigued me right away, but having reviewed plenty of promising hookup apps with too few users, I was skeptical. A glance at the traffic stats, though, got me excited: Go3Fun’s website gets nearly 125 million visits per month. That’s a serious number, suggesting plenty of potential partners. Naturally, I couldn’t wait to dive in.
Going Fun with Go3Fun
I initially assumed the app was called Go3Fun, just like the website, but in the app stores, it’s simply 3Fun. The website name is basically a call to action: Go 3Fun. A little clunky, but all the good domain names were taken.
Unlike most dating apps, 3Fun doesn’t have a web version. Go3Fun.co exists mainly as a promotional page to direct people to the official app stores. You’ll find some FAQs, safety tips, and legal info, but that’s about it.
This might have been a bad business move a decade ago, but in 2025, almost everyone is comfortable with mobile apps. The website still offers some key stats upfront: 2.5 million active members are ready to meet and mingle. That’s a huge number, and combined with the traffic stats, it’s clear this app isn’t struggling to find users.
Inclusivity is also a major selling point. 3Fun welcomes singles and couples of any sexual orientation, which makes sense for a threesome-focused app. Chances are, in any group of three, at least two of you share the same gender identity.
Getting Started with 3Fun
Since there’s no login on the website, I grabbed the official app from Google Play. Installation was fast. The app’s logo is… suggestive—a little pair of panties. You’ve been warned.
The app opens with a few intro screens that mirror the Go3Fun website. One notable difference: screenshots are disabled, which could be either a blessing or a curse depending on your intentions.
You can log in with your email after signing up, but initial registration requires a phone number or a Facebook account. I went with my phone.
During signup, you provide your gender, sexual orientation, and who you’re looking for. The app offers over a dozen options, including Polysexual, Heteroflexible, and even Asexual—a curious choice for a threesome app, but hey, inclusivity matters.
Profile setup includes a brief bio and photos. 3Fun encourages discretion, suggesting you show just part of your face if you’re shy. They also give you the option to block contacts from your phone, a feature I wish more hookup apps offered. No awkward Family surprises here.
Using 3Fun
Once inside, the app is simple and intuitive. Instead of swiping, you click an X or a heart to indicate interest. Free users can’t set custom locations, so if you want to explore elsewhere, you’ll need a VPN.
Within minutes, I had a notification under the Prospects tab—someone liked me. Naturally, they hit me with a paywall: full access costs $30 per month, which is reasonable for a niche app with a solid user base. They also offer discounts for longer subscriptions, like $10/month for six months.
Paid features unlock unlimited Likes, messaging without matching, seeing who liked you, browsing other locations, and boosted visibility—very useful in such a busy app.
Final Thoughts
Go3Fun.co promises a lot for a threesome-focused dating app, and it actually delivers. Signing up is quick, browsing is easy, and the user base is active and engaged. You can start exploring without paying, which is perfect for testing the waters.
If you’re adventurous and looking to join the threesome scene, 3Fun is worth a try. I know I’ve got a few prospects to follow up with tonight.
