What is it about speedos that is such a turn on?

Adult male in 20’s with an infatuation with speedos/wrestling trunks. Whether it’s a pro wrestler, guy at the pool swimming laps, or a guy wearing a speedo by the pool/beach, something just really turns me on. I actually consider myself mostly straight too. Wanted to get peoples thoughts on what the psychology is behind gawking at a pro wrestler or speedo-wearer. Any of the following?-overall confidence in their body (in shape or not) -confidence/cockiness in sex appeal -the risqué-ness of an exhibitionist -the sexualization/focus on the package/butt -exposure of body parts that are generally covered -the wearer wearing it to show other guys/girls he wants sex -the wearer allowing others to see all of him -specific to wrestling, the wearer likes an opponent showing off his body for him via holds, moves, pins -indication of sub or domSpecifically in pro wrestling, very often a hunk plays the role of a jobber and gets destroyed in the ring, body put on display and spread. What goes through the wrestlers head when they know they are going to go out there and lose the match, and still choose to wear trunks that ride up their ass and show their package so obviously.Message me to chat more
