Why was I getting weird looks?

I just did the twin falls hike in Hawai and I decided to wear my tight swim jammer because it’s the only type of swimming suit I wear but I seemed to be getting a lot of weird looks and people laughing at me i am not sure if it was because of the bulge or just the tightness but I felt comfortable and I was wearing them in an appropriate way the main reason I wore them was to go swimming but they are also really comfortable to walk in so I don’t chafe down there also if I sweat it won’t get see through like my bike shorts
