I live in a small city/big town what you do is go to whatever drug store you have. Grab a box of condoms, i’m going to suggest SKYN condoms. They’re thin, crystal clear and durable. If you have trouble finding them, they come in a black and gold little box. If they don’t have them any condom will do although you really should read the box. Measure the circumference at the widest part of your shaft, normally right around the middle, that’ll prevent the condom from just slipping off, which is the issue some asian guys have with condoms, they’re like long grain rice, long a thin. South east Asian’s make up like 1/3 of the world population...it’s not a coincidence.
