I Thought I Was Just Imagining It—But My Size Really Shrunk in My 20s

I know this sounds crazy, but I swear my penis was more significant when I was younger. And no, this isn't some weird illusion or one of those “I used to be huge in high school” stories. I’ve got proof—or at least, I used to.

Back when I was around 15 to 18 years old, I went through a phase a lot of teenage boys do: I was obsessed with measuring myself. Like clockwork, I’d whip out the tape measure once a week and note my stats. Six inches. Every time. Like a badge of honor. My erections were intense, random, and frequent—even if I wasn’t turned on. It’s like my body was constantly on standby.

Fast forward to now—I'm in my mid-20s, and things aren’t the same. I was shocked the first time I measured and only saw five inches. On bad days? Four and a half. I thought I was losing it. Was I remembering wrong? Measuring wrong? Was it all just in my head?

Nope. Something definitely changed.

What Changed?

Here’s what I’ve figured out, and maybe it’ll help someone else going through the same confusing experience.

1. Erections Aren’t the Same

Back in my teens, erections would just… happen. No warning. No reason. I could be bored, tired, or just sitting through a class, and boom—full steel. Now? It takes actual stimulation. Mental and physical. And even then, it doesn’t feel like the same kind of firmness or fullness I had before. It’s like I have to earn my erections now.

What’s wild is that when I was younger, these spontaneous erections seemed to stretch everything out more. They were fuller, harder, longer. Nowadays, they feel more dependent on mood, energy, and even stress levels. And if I’m anxious or distracted, forget it.

2. My Foreskin Acts… Different?

Here’s something I didn’t expect: my phimosis actually became more noticeable as I got older. When I was younger, erections would naturally stretch my foreskin taut, and I didn’t think much of it. Now, even when I’m fully erect, the foreskin doesn’t pull back completely—it forms this little “tip” of extra skin.

I haven’t injured it, and I don’t have pain, but it’s like something got tighter with time. Or maybe less elastic? Either way, it's made my erections look different and, honestly, made me more self-conscious.

3. The Weight and Activity Factor

I’d be lying if I said I was as active now as I was as a teen. Back then, I played soccer and biked everywhere. Now I work from home, snack too much, and rarely exercise. I’ve definitely gained weight—especially around the belly—and I’ve read that excess fat in the pubic area can make your penis appear shorter.

Apparently, even just a 10–15 lb weight gain in the lower abdomen can hide up to an inch of penis length. I always thought that was some gym bro myth, but looking at myself in the mirror now? I can’t ignore it.

4. Pre-Diabetes and Circulation

Here’s the part that really made things click: I was recently diagnosed with pre-diabetes. At first, I didn’t connect that with my sexual health, but then I started digging.

Turns out, high blood sugar over time can damage blood vessels, including the ones responsible for erections. Poor circulation = weaker erections. That might explain the difference in firmness and fullness. I also read that early signs of erectile issues are sometimes one of the first symptoms of pre-diabetes or insulin resistance.

So yeah… my shrinking erection might have been trying to warn me about my actual health.

Why This All Matters

I debated even talking about this publicly, because let’s be honest—it's not exactly barbershop conversation. But after Googling “why does my penis look smaller in my 20s?” and seeing forums filled with guys asking the same thing, I knew I wasn’t alone.

And I think more guys need to know: Your penis size isn’t set in stone. It can change. And sometimes, that change is trying to tell you something more important.

What I’m Doing About It

I’ve started making changes—slowly but surely.

• Diet & Exercise: I’m focusing on dropping that stubborn belly fat. If I can reclaim even half an inch from that alone, I’ll take it.
• Foreskin Stretching: I’m looking into gentle stretching techniques to help with the phimosis. I’m avoiding surgery for now, but I’m being proactive.
• Managing Pre-Diabetes: I’ve cut back on sugar, upped my fiber, and started tracking my blood sugar. It’s work, but worth it.
• Daily Erections: Sounds weird, but I’m trying to encourage daily erections. It’s like exercise for your penis. The more you “use it,” the better blood flow and tissue health stay.

That’s actually what led me to discover the Penis Enlargement Remedy Program—hands down the best exercise-based system I’ve come across. Inside, you’ll learn powerful penis enlargement exercises that can increase your size by 4.4 inches in just 90 days. 

It includes ancient Arab techniques that reportedly helped boys reach over 10 inches by high school, erection exercises for rock-hard performance on demand, a go-to stretch that boosts length instantly, and even secret 2-minute routines to last longer in bed. 

There’s also a simple method for testicle enlargement, thickness-enhancing moves for more sensation and pleasure, and exercises to increase ejaculation volume in just a week. Trust me, this stuff is wild—in a good way. Go try them and let me know how they worked for you. 

On the next page, you’ll even take a revolutionary quiz that predicts how big stem cells can make you, based on your size, age, and race.

And most importantly, I stopped obsessing over numbers. I’ve realized it’s less about hitting a perfect measurement and more about feeling confident, functional, and healthy.

Final Thoughts

So if you’ve ever thought, “Wasn’t it bigger before?”—you’re not crazy. And it doesn’t mean something’s wrong with you. But it could be your body’s way of whispering that something else needs attention.

Don’t ignore it. Your body’s smarter than you think.
