Came across this article discussing how to correctly measure your, ahem, “unit “. It’s important to know your penis size for various reasons.

For example, being properly fitted for condoms. It’s not a “one size fits all” believe it or not. If the condom doesn’t fit properly, besides being uncomfortable, it could lead to unwanted pregnancy or contracting an STI. Monster cock and teeny weeny custom sizes are available online.

For some of you sissies, cucks, and subs, it’s important to know your flaccid AND erect dicklet size to purchase a good fitting chastity cage. More often than not, multiple cages are purchased due to not knowing your true tiny size. That can get expensive with some of these costing upwards of $300, and I don’t personally know of any companies that will exchange or refund opened packages. Also, remember to take multiple measurements to get an average for this purpose. Measure when it’s cold , and when it’s hot out, then average the #s.

Lastly, I can’t tell you how many guys have told me they’re “X” inches long , and the reality is that most of the time they’re at least 1/2” to 2 full inches smaller than what they’re claiming. Oddly enough , it’s never been the other way around.

Whenever I’ve measured a dick length, I take a tape measure or ruler and I start from the torso to the top of the tip. I place it over the top center of the dick ( not the side and definitely not underneath ). Tip: Measuring from the side can actually shorten the true length , especially if it’s at an angle, so measure from the top center to be sure. The article says to push into your torso until you hit your pelvic bone. I disagree with doing this because some heavier set guys will gain sometimes a few inches by doing this. I feel like it’s the equivalent of measuring my waist size holding my breath and sucking my gut in… kinda cheating , no? So unless you’re planning on wearing male SPANX, I wouldn’t measure that way. I guess it depends on what you’re measuring for exactly ?

With regard to girth, use a flexible tape measure , or cut a piece of ribbon or paper , mark it , then lay flat along a ruler. Measure the fattest / widest part of your cock. For most guys that will be at the base , but I’ve seen some that were fatter near the head .

Hope this helps :)
