The first time i ever bought condoms, i bought the magnum xl's, and I was really nervous so i jsut went thru the self checkout so i wouldnt get "the look" so i pay and am headed out the store and the god damn security thing goes off........i'm like are you serious. so the old man greeter at Wal-Mart is like "oh lets just take a look at what dint scan" FACE PALM He pulls out the Box of XL Magnums and smiles looks at me and says, " These Jimmies never scan right" gives me the box back and says "Take er easy big fella" It was horrible haha
Haha exact same thing happened to me! Worse was I had to ask some women (they were in a pack!) workers where the condoms were. They were right in front of me.
Then on the way out the alarm went off, I just showed the security guy the receipt. Lucky for me it was almost midnight and no one else was in.
But on topic:
Large size condoms aren't a marketing ploy. Well certain brands anyway. Such as Magnum XL, Pasante Large, Skyn Large. They are actually large size condoms and can be more comfortable than others.
Featherlite seem to be between regular and large size, from my experience. But not sure, only had a brief encounter with those.
Then you have things like Condomi XXL which are just regular sized or maybe even smaller.
Also there is a thread called "The Big Don't Show" or something...most well endowed men don't actually show. Basically if you wear boxers and comfortable trousers, your cock will hang down your leg/inner thigh and not be very visible.
Whereas if you wore briefs and maybe tighter fitting trousers, you would show a bulge of some description.
