(NSFW) Protection size too small have any suggestions?

I use to assume that after having sex for while ( like 30mins to an hour) that I must of just went soft. After having sex with my lady I decided to take condom off as she was ok with it, as she had protection.

What a world of difference. I then tried a little experiment and masturbated with the condom on. It took a while to get hard, at which point clearly see it was pretty tight where the ring is. What I realized was if I had a “raging boner” or was very intense sex then I don’t notice it. However anything less and it is literally choking my penis. It even lift a ring print at the base…

Anyways I have tried “bigger” condoms even XL magnum the problem is all these condoms seem to have longer lengths, but are almost same if not the same for the circumference. I even went to the erotic shop in town and was suggested condoms. Same problem! They all just get longer, but not wider.

If the Magnum thin was just a bit more “loose” at the ring or circumference part of it, I think I’d be golden.

But finding it seems to be. Impossible. Suggestions??
