Every condom is made differently. If a person looks at different condoms one will see that some condoms fit tight some fit more lose. I don't like the feel of basic condoms, without some water based lube, I would never get a standard condom on. I like the fit of magnums, with girth but the length is a little to long for me (right now...not after i succeed with my PE goals). If you buy a condom like trojan ectasy or trojan her pleasure, they are made the same girth size as a trojan magnum without the extra length (and they have better head room...no pun intended). If I had an EQ of 10 i would be between 5.85-5.95 but i never get a EQ of 10 the best i get is eq of 6 or 7. which leads to me having a 5.5EQ ...
I say all that to say, Be proud you are in the Magnum club..I am, but if its too long in length find an alternate condom that fits the same but length is a little better suited for your personal needs.
