So yeah I am runner. I have been running longer time now.
i run in tights and don't wear any shorts to cover my stuff, bulge and ass visible.
When I was starting to run like this I remember i thought it's so embarrassing to have your bulge visible but on the other hand i think having shorts on tights looks lame as h*** and it's not very comfy ( another layer = more heat ).
When I was starting my running adventure I was running at night. But after some time i gained courage. Also I liked the idea of showing off my body, my legs are nicely build ( slim but you see they are practiced/trained ) and I am proud of them.
The first thing was the bulge actually after all this time I must admit most people won't check you out down there unless you are very big or at least erected. Here comes first sad truth of running in tight lycra. Well since it's tight it will block your member from erecting too much. So my 6,5 inch in my running spandex is something close to 4 inches or even less. Still even when it's not that big but erected people will look. but yeah now they are looking at your small d*** and probably thinking what a small one. Learning that was embarrassing and now I avoid any erections while running. hopefully this does not happen often. When you run and don't think about silly things your safe.
Btw when I am not erected it's nearly flat out there. It is also ofc embarrassing but I got used to it. Nearly no one looks, guess there is nothing to look. I was also 2 times mistaken for woman which was rather humiliating experience ( one time by guy he seemed to wanted to smile to me but when saw my face and understood his mistake his face ( he was on bike so he was passing me ) turned to something close to confusion with a bit of anger. ;-)
So after time I got to point i think it's not the bulge that is the most embarrassing thing. It's the spandex that clings your ass and shows off your buttocks fully exposed.I have very nice ass and I have observed on numerous occasion people sticking their eyes on my ass. Did not noticed it at first since well you kind of need to turn around to see this happen but after some point i was very sensitive on this topic. What is more also big representation of man was cough doing that. I had bikers slowing down to nearly bowl some time behind me running. While waiting for elevator a girl simply walk just behind me . She was nearly on my back. Also a fellow runner girl while passing me ( I was fighting her for 20 min running as hard as I could ) after I gave up to let her pass me and slowed down quite much. Did she pass me? Yes after like 5 min running slowly as me camping my back. Also very many other occasions.
Maybe I kind of overthink this but at some point this brought my attention.
But the guys that check your ass. This was always the most embarrassing thing tbh.
