Your penis size does not matter (much) when choosing a Fleshlight. Standard Fleshlights can accommodate penis lengths of up to 9" and girths up to 7". Both these measurements are above the 99.99%ile, which means that more than 9999 men out of every 10,000 can use Fleshlights comfortably. Some of the stroker sleeves and the Fleshlight Go are smaller, but the vast majority of men will fit a Fleshlight.
