Dian, thank you for your post.
I am commenting on just one small part of your post. To paraphrase what you wrote: you shared that you are aware of men with big penis seeing another big penis man "showing off at the urinal" and they want to "sidle up" and compare and see who is longer and thicker and biggest overall.
Heck, over the decades, more than a few times....quite a lot of times...I have had women, hear about me from their friends, their coworkers, mere acquaintances, and even their close female relatives....and they told their own "horse cocked" boyfriend or husband or lover. And....the part that is the wanting to "compare"...is I have had these complete strangers....many times....a couple or even a small group....just "out of the blue", with my usually knowing none of them, find out who I am and where I live, then on their own, no prior contact at all....completely unexpectedly to me....the couple or the small group...just show up and knock on my door and explain they have heard about me and want to see and show me and "prove to me" that they were "longer" or "thicker" or just "bigger" than I am...or that their loads are bigger than mine or something to compare not only their size to mine, but their virility to mine...
Sometimes the women with the man or with the group... seem to be, at first, embarrassed...but also excited and almost "in heat" from the way their faces and bodies seem to be reacting....
IF...the people at my door, seem otherwise "harmless"...and not "gross" or "dirty" or "sleazy" or "dangerous" in some way...those "alarm bells" will always cause me to politely decline and ask them to leave and not allow them entrance to my home....BUT....a very BIG BUT...IF they seem otherwise "safe"...and at least somewhat attractive to me, women who are there too.....and my mood is fine with it, and what I was interrupted doing can wait....I have been known to invite them inside....and right there in the foyer....no sense bringing everyone in to all of my home....told them to pull theirs out and get hard and let's decide this. After all, that is why they found me and showed up at my door...they wanted this...so my taking that forward approach always seems to surprise every one that has been allowed inside my door.
And since I am a nudist at home...and I only put on a long, ankle length robe I keep nearby for the odd and...rare....door bell ring (even if it is just a delivery)....I wait until the "stud" who is there to "beat me" is nude and his own efforts and with the help of his wife and/or girlfriend(s), and he says he is fully hard...then I open my robe, and still flaccid....let them all gawk...and that is always obvious that is "enough" to settle the matter without any argument....my flaccid "beats" their erection...no need for my to work myself erect for all to see who "won"....but
But once in a while, I will hear...the objections...as an example the comments similar to: "but can he get his hard, soft doesn't win if he can not get hard"....or some such argument.
Then I tell them all to take out their wallets...pool their cash and such on a table...and that is mine to prove to them I can get hard. I also tell them that if I do get hard...which woman or women, right then, will volunteer to take my cum on her so they can remember this....almost always the women all "volunteer"...only some wives have been hesitant about volunteering...not sure how their "huge cocked" husband will react to their "volunteering"...so I share that if they if their are no volunteer(s) no getting hard, and they can leave and think whatever they wish about my being only "won" flaccid....and every time they have been told by their husbands or boyfriends to "volunteer"...and then, they have always been eager to do so once they have "permission"....and they all, both the guys and the women present....never forget what happens next...what they saw and what they will never forget.
And....over the years...some have become more than just people I did not want in my life...I have had "stalkers"....those who will not just leave me alone....so I have had to go and get, several times, warrants to keep some folks away from me and my life.
It is what it is...but sometimes I am amazed at just how forward some folks can be...insistent....as if I am not a real person and I exist...or rather my endowment exists...just for their life.
