Condoms should be more like shoes. You go into a shop, tell them your size and you get shoes that fit your feet. Not so with condoms. Aside from the occasional extra large condom brands, condoms come in one size: A width of about 52mm. Penises, however, come in many sizes. This leaves many men squeezed into condoms so tight they cut off circulation (and impede erections) or so large they're floppy and nonfunctional. MY.SIZE condoms fit on nearly every penis size.
