What is the reason behind some people wearing trunks instead of speedos when swimming in pools?

Most men are super self conscious believe it or not the new programming from pornographic films, and movies with our favorite actors, heck even the tic tok gray sweat pants videos. Men are just as self and body conscious as women. However men hide it or reflect it on others. That being said most men believe that there Johnson needs to hang low or have a big prominent bulge in there clothing. The ones who wear speedos or g strings like my self we are confident or hung like a mule. I am the confident one nothing on me is considered hung at my terrifying 3 inches of furry in flaccid state. But most men would be way too shy to strut there stuff due to other men around being what I would call shower not a grower. I would say 90% of your growers would not dare put on a speedo being that they psychologically believe that women want this giant cock man. Don't get me wrong some women do want that your size queens and such cool good on you girls go get what you deserve sweetie i can't help you. But most momen don't want all that dick most women truly want about a good 5 to 6 inches and a man who is willing to take the time and show her the meany sensations of the body. I may not be hung but damn if I can't roll my rs and eat a pudding pack without a spoon. We all have strengths and weaknesses. I often compare it to what women are programmed as most women believe that all men want is big tits tiny waistline and ass. Worng there are plenty of those out there due to starving your self and being always in a bad mood give me a real woman who eats a burger got some weight on her is happy in my arms will suck and rock my world have fun exploring diffrent fantasy both vanilla and extra dirty. I'll take the sweet beautiful full figured any day. But that is why trunks shy/ conservative guys or men who are nor confident. Speedos more confident, or well hung, don't give a f what anyone thinks of them guys.
