I may be naive and certainly despite my age (76) very ignorant but size matters. How do I learn what size I need? How do I measure my penis!??
(Thanks for being here, where else on the planet could I safely ask this question?)
I honestly think it’s a matter of trial and error. One manufacturer has a downloadable size chart which they then match to their ideal-for-you size condom. I emailed them and said, just give me the width and length of your products. They refused.
If you find a condom is too tight (or too loose) it’s not rocket science to try one that is a few mm bigger (or narrower). Some online suppliers do a very large range of sizes.
Bear in mind some of the very thin ones don’t stretch — which can make a difference when choosing width.
I recently threw out quite a lot of shit (for me) condoms. I’ve tried I think at least two dozen brands before finding what I feel suits me. It is, after all, quite a
personal and individual item!!
