from the age of 14 till a bout 25 the gym and showers were my only available outlet for sex [i lived in the wastelands of suburbia ] i not only looked/stared at guys changing or in the showers ,but would always try and be as provocative as possible is order to get a response. there were some guys you knew not to stare at but the vast majority of guys would look ,often get semi hard in response or join in with the show.but all that aside there were also guys who would get hard just from the whole naked thing and for those i would just sit back and admire the show
