Was wondering if anyone had ever got a hardon in public.

It used to happen all the time and especially in porn shops.

Was kind of my natural state back in the day

Yea, often. As a kid on the bus on the way home from school. Sometimes missed my stop because it was so obvious. In gym showers, and at my desk. Spontaneously almost anywhere!

Yes I have....sometimes get them at work, and when out and see a girl I like the look of as start to think about things I'd like her to do to me or for her to let me do to her. Work is worst as it usually happens as I have to get up from my desk.

I think my question would be: "Are there any guys out there who have NOT gotten a hard-on in public?"

I know I have - dozens of times.

always get hard in public and have done since It was even big enough to notice

before going into a peep show or adult bookstore or porn shop I always stroke it in the car until it is rock hard so that I walk in wide legged. Cock making a huge tent as I walk on the sidewalk and then stand in line for tokens. I love slowly walking through the aisle and then from booth to booth with that tent pole out rock hard for everyone to see. I always wear a pair of sweat pants that show my hard cock off great when I do this. Once while walking around I let the hard head poke out over the top of the waist band as I entered the adult only area. Drove people crazy to see my hard cock trying to get free and drove me crazy watching them look at it. OMG I love showing off my hard cock.

You never played cock tweaking in High School. Approaching a bud in the hallway, deftly and discreetly reach over and give his junk a little tweak through his trousers. As you keep walking, turn around and wonder why he suddenly started walking so funny!

When I was the7 the grade, 12 yrs old. Our bus driver flew down residential and bumpy roads. When the bus cam around this sweeping turn, I there was a huge bump we were going to hit. of course all of the little bumps, and the anticipation of upcoming dry orgasm (yep still dry thank God!), had me hard as a nail. Now, I was at least averagely endowed, so had anyone in my sea they definitely would have seen that I had an erection!
In fact, finally, one other boy and started "riding the bus" regularly. Some Years I spoke to a Psychologist and found this to be quite a common occurrence. Still love those stiff suspensions of busses today.

Way too many times to count, I love stroking in my car in public and in restrooms

I lost count a long long time ago....

I haven't had a random boner in years, and I'm thankful. Used to be hard all the time. I dated a girl once who never saw my dick limp for two years.

Used to get so hard in public for no reason that I'd go to the bathroom and jerk off to make it go away. It was painful to sit around with a boner.

anyone else?

OMG! If I was hung like you, I'd have done the same thing! You are one HUNG dude for sure! Wish I had seen it!
