Nope, I'm not dumb. First of all, I'm a grower, so whenever I workout, it definetely won't cause that big of an impression. So I'm honestly asking from the perspective of someone who doesn't know first hand what it's like to carry an anaconda down my shorts.
But the thing is I believe we may have a different perspective on what should be considered vulgar.
I've said in some other thread that I think there is a difference in blatantly showing off and simply not being able to hide what you have.
Why should a 44DD busty girl have to cover her breasts in 10 layers of clothes just so other people don't get offended? It's her body, she can't do anything about it. If someone isn't feeling comfortable looking at her boobs bouncing with the workout, then they should look the other way and just focus on their own workout.
Same with dick size. If you're naturally hung, why should you have to crush your junk into the tightest underwear you can find just so others don't get bothered by your bulge? They shouldn't be looking at it in the first place.
It's a whole different thing if you're going commando on a pair of white mesh shorts. But even then, you already know you'll be causing a sensation and you're probably doing it on purpose.
People starting comments? People should just mind their own business and stop getting in to someone else's private space.
But, as I said, this is just my view and I can totally understand and respect your discomfort. I was honesty just trying to understand what the problem was.
