The Benadryl Incident
An SPH Experience by limpnubguy.
It happened years ago, long before I met Sarah. I was in my early twenties, living in a cramped studio apartment, working a dead-end job, and desperately trying to figure out who I was sexually. I’d always been self-conscious about my size—even then I was barely pushing 4 inches hard—but I had this strange, obsessive curiosity about what I could get away with. What boundaries I could push. How far I could take things before getting caught.
I’d read something online about Benadryl causing temporary shrinkage in some men. Not erectile dysfunction, just… shrinkage. A temporary reduction in flaccid size. Most guys would be horrified by that. But me? I was intrigued. Because I had a theory: if my dick got smaller, maybe people wouldn’t notice it as much. Maybe I could get away with things I normally couldn’t.
I know how that sounds. It sounds insane. But back then, I had this fantasy about being caught naked, about someone seeing my small cock and either laughing or—in my wildest dreams—being turned on by it. It was a weird mix of exhibitionism and humiliation kink that I didn’t have words for yet. I just knew I wanted to test it.
So I decided to run an experiment.
It was a warm Saturday afternoon in early summer. I’d just picked up a 24-pack of Benadryl from the pharmacy—the generic kind, diphenhydramine, 25mg per capsule. I’d read that the shrinkage effect was most pronounced at higher doses, so I decided to start with four capsules. A hundred milligrams. Enough to make me drowsy, but not enough to knock me out completely.
I swallowed them with a glass of water and waited.
An hour later, I felt it. Not just the drowsiness, but a strange tightness in my groin. I went to the bathroom and dropped my pants. My dick, normally about 2 inches soft, had shriveled to barely an inch. It looked like a frightened turtle pulling its head into its shell. The skin was wrinkled, the head barely visible. It was almost comically small.
And I loved it.
I stood there, staring at myself in the mirror, stroking it gently to see if it would get hard. It did, but barely—only reaching maybe 2.5 inches, a full inch and a half smaller than my normal erection. It was like my body had become a caricature of small-dick insecurity.
But the weirdest part was how calm I felt. The Benadryl had a sedative effect, sure, but it was more than that. I felt detached, almost clinical. Like I was watching myself from outside my body. And that detachment gave me courage.
I decided to test my theory.
I lived on the third floor of an old walk-up building, and my apartment had a window that faced the alley below. It was a narrow alley, mostly used for garbage pickup, but occasionally people walked through it as a shortcut to the main street. I opened the window, the warm summer air hitting my face, and I stood there, completely naked, looking down at the alley.
My heart was pounding. My palms were sweaty. But my dick stayed small and tight, that Benadryl shrinking keeping it tucked away like a secret.
I waited.
For about ten minutes, nothing happened. A few people walked by, but they were looking at their phones, or talking, or just generally not looking up. I was about to give up, feeling foolish, when I heard voices approaching from the end of the alley.
Two women, maybe in their late twenties, walked into view. They were laughing about something, carrying shopping bags. I froze, half-expecting them to look up and scream. But they didn’t. They just kept walking, chatting, until one of them—a blonde in a sundress—happened to glance up.
She stopped mid-sentence.
Her friend, a brunette in jeans and a tank top, noticed her friend’s sudden silence and followed her gaze. Both of them stared up at me, standing naked in my third-floor window.
I should have been mortified. I should have ducked back inside, slammed the window shut, and never spoken of it again. But I didn’t. The Benadryl had made me calm, almost numb. And somewhere deep in my kinky brain, I was thrilled.
They stared for a few seconds that felt like hours. I didn’t move. I didn’t cover myself. I just stood there, letting them see every inch of my tiny, shrunken cock.
The blonde’s expression shifted from shock to confusion to… amusement. She nudged her friend and pointed. “Is that a… is that a dick?” she asked, her voice carrying up to me through the warm air.
Her friend squinted. “I think so? It’s so small though.”
They both laughed.
“Oh my God,” the blonde said, clutching her shopping bag. “That’s so pathetic. Look at it. It’s like a little button.”
“I bet he thinks he’s so hot,” the brunette added, shaking her head. “Standing there like he’s got something to show off. And that’s what he’s working with?”
They kept walking, but they kept looking back, laughing and whispering to each other. I watched them until they disappeared around the corner, my tiny cock still on full display.
I felt a rush of conflicting emotions. Embarrassment, definitely—my face was burning red. But also arousal. A strange, twisted arousal at being seen, at being laughed at, at having my inadequacy confirmed by two random strangers.
I closed the window and sat down on my bed, my heart racing. I was hard—well, as hard as I could get with the Benadryl in my system—and I stroked myself to a quick, quiet orgasm, imagining those women telling their friends about the weirdo with the tiny dick they saw in the window.
I thought that would be the end of it. But the next day, I heard someone in my building talking about “that creep on the third floor” who’d been “flashing people from his window.” The rumor spread. People stared at me in the hallway. My landlord gave me a warning about “indecent exposure.”
I never did it again. The shame was too much. But the memory stuck with me, that strange experiment with Benadryl and exhibitionism and humiliation. It was the first time I’d ever put myself in a situation where my small size was the center of attention, where people laughed at it, where I felt the strange cocktail of shame and arousal that would come to define so much of my sexual life.
Looking back now, after everything with Sarah and the table and her bull, I wonder if that moment in the window was when it all started. When I first realized that my small cock wasn’t just a source of insecurity, but a source of something else—something dark and thrilling and deeply, deeply humiliating.
Maybe that’s why I stayed with Sarah. Maybe that’s why I let her fuck other men, why I let her mock me, why I let her grind on a kitchen table while I jerked off like a spectator in my own marriage.
Because somewhere deep down, I’ve always wanted to be seen for what I am. A small-dicked loser who can’t satisfy a woman.
And the Benadryl just helped me show it.
The End.
