Nothing says summer like a cookout, and what’s a cookout without wieners? Popstar is celebrating everyone’s favorite frank and the star of the male anatomy: the penis. Whether you call it your manhood, junk, member, or “Steve,” there’s no denying that penises are fascinating little (or sometimes not-so-little) creatures.

Forget boring anatomy class; these penis fun facts and bits of trivia will have you side-eyeing your own package like it just told you a dirty joke. From the first erection fetus to penile fracture facts that’ll make you wince, we’re diving deep—because we always go deep—into the wild world of the penis.

Think your first stiffy showed up sometime during middle school while you were awkwardly watching Baywatch reruns? Nope. The penis starts practicing way earlier. In fact, some ultrasounds have captured penis development in the fetus complete with erections.

Doctors think these mini woodies happen during REM sleep, which means your penis is working overtime even before you open your eyes for the first time. And yes, some babies make their debut into the world already at full salute. If that’s not a strong entrance, we don’t know what is.

“Morning wood” sounds cute, but the clinical term is nocturnal penile tumescence (because scientists need to ruin everything with overly complicated words). It doesn’t just happen once when you wake up—most people with penises have three to five erections during the night.

So, when you’re waking up with a tent in the sheets, it’s actually the end of a late-night performance, not the start of something new. Think of it as your body’s way of saying, “Congratulations! Your plumbing still works.”

Yes, this is a real thing. The angel lust phenomenon is when an erection happens post-mortem. Totally unrelated to angel dust, this eerie occurrence is due to spinal reflexes firing off after death. Morbid? Absolutely. But also fascinating—because apparently, some guys really do take “till death do us part” seriously.

This might be the best confidence boost you’ll hear all day. Roughly half your penis is tucked inside your body, doing its thing like a behind-the-scenes roadie. If your visible length is five inches, you’re technically rocking ten. Sure, you can’t show it off, but your pelvis knows the truth.

And if that doesn’t make you feel like you’re packing heat, consider pairing your biology with our Popstar Volume + Taste Supplement to take your game to a whole new level.

The grower vs shower penis debate is as old as time. Growers look modest when flaccid but transform into superheroes when erect. Showers? What you see is basically what you get. Neither is better, but let’s be honest, growers get the most satisfying before-and-after reveal.

In the U.S., circumcision is the default for most, but globally, non-circumcised penis statistics show that the majority of the world keeps the natural look. So, if you’re traveling abroad, don’t be surprised to encounter an “uncut gem” or two. Variety really is the spice of life.

“Big feet, big meat” is about as accurate as saying corn flakes stop people from touching themselves (more on that later). A 2002 study officially squashed the penis and shoe size myth, finding no connection between your kicks and your stick. Height, age, and even finger length are better indicators—but honestly, we’re all unique, so forget the measuring tape.

You read that right. Even though there’s no bone in there, a penile fracture can happen if the erect penis bends sharply—usually during vigorous sex. Cue the horror soundtrack. The most common culprit? Reverse cowgirl. So, if you’re into acrobatics in bed, maybe communicate before going full Cirque du Soleil.

Your penis can shrink due to aging, lack of blood flow, or certain medical treatments. While this isn’t exactly one of our “fun” penis trivia tidbits, it’s important. Healthy circulation is everything. That’s why some men explore supplements or tools that keep blood moving and confidence growing.

Hint: staying hydrated and sexually active helps. And no, cold water pools don’t count as permanent shrinkage (even if you’re convinced otherwise).

Ah yes, good old Dr. John Harvey Kellogg. He believed bland foods like corn flakes would kill sexual urges. Spoiler alert: they didn’t. If anything, they’re better with sugar—and masturbation is now recognized as a healthy and normal activity. Sorry, Kellogg. You can rest in peace knowing we’re still “frosting our own flakes.”

While we’re busting myths, let’s talk size. The obsession with bigger being better is tired. Studies show most partners care far more about technique and intimacy than sheer length. If you’re worried about how you measure up, remember this: confidence is the sexiest thing you can bring to the bedroom. That, and maybe some Popstar Delay Spray for extra staying power.

Whether it’s penis trivia about fetal erections or debunking size myths, knowing more about your body can help you appreciate it (and use it) better. Penises are complex, resilient, and, let’s face it, endlessly entertaining.

Want to show your penis some love? Consider boosting your confidence and performance with Popstar Volume + Taste Supplement or our Delay Spray —because every legend deserves a sidekick.
