It’s all in the mind. The only way you can experience that “power” is if you accept and embrace the size of your cock, whatever it is.
I can attest from first hand experience that having a big dick in and of itself does nothing. I naturally have an extremely above average penis, length wise, and it’s slightly above average in width. Yet that didn’t stop me from growing up thinking that I was small. I didn’t ever (still haven’t) seen any many erect outside of porn, and since I didn’t grow up in sport, I almost never saw the inside of a locker room (and kids in PE never stripped nude). So I was totally warped regarding what other guys looked like, erect and flaccid, and from my perspective I was way smaller than guys in porn. I was also a very fat kid. I measured my penis the first time in my late teens or early 20s and was around 6 inches in length, and felt that was small at the time. It wasn’t until I lost a lot of weight did I measure again, and to my shock I was over 7. I read up on averages and the such, saw that I was way above, and yet still didn’t believe that I was well endowed at all. I ended up losing even more weight down the line, after going up and down the scale, only to see that my dick actually, at it’s hardest, is a little over 8 inches long.
I have accepted that I technically have a big dick, but I don’t think of myself as truly endowed at all. Years of inadequacy don’t just get erased because you find out a fact. My baby adores my cock, she tells me frequently how much it drives her crazy, and it’s obvious when we have sex how satisfied she is. And sure I love hearing that, but it never really sinks in that I’m a big, well above average guy. It’s all in the mind I tell you. I’m sure there are plenty of guys working with less dick than I am who feel much bigger and more “powerful” in their size than I ever have.
