Is it normal im completely obsessed with exercising my butt muscles?(im a dude)

it all started long ago when i was about 10 years old,long story short i was obsessed with how high and far i could jump. it mostly stemmed from seeing video game characters and their jumping ability which might sound stupid i know but modeling yourself after a video game character at 10 isn't too crazy i suppose.

i wondered "what muscles control your jump,how do you work them,etc".After a little research i found the whole body was involved in the jumping process but it was intensive on the lower body and the glutes seemed to have a very important role,so i began learning a great deal about various exercises,squats,lunges,isometric glute squeezes,anything and everything to get me to jump better.These exercises defiantly improved my jump!

Now being very young i still knew that there was something about a boy exercising his butt that society might frown upon,its just taboo i suppose,there is a ton of sexual emphasis placed on the butt which i did not fully understand.Then in high school things got awkward.The girls paid A LOT of attention to my butt,girls i never met would talk about it and obsess and grab it. Years of lower body exercises made my butt big and shapely,much more like a girls i guess which made me feel weird because the girls seemed to love it but i assumed boys would think i was "gay" for exercising my ass.

AS time went on i was not only obsessed with my jumping but attention from girls made me obsessed with butt isolation exercises in general.These close friends encouraged my glute growth and convinced me to take the "womens" PE class...no straight boy dared to take it but i did.It was awesome,30 girls,1 boy,plenty of glute exercises to be done,there were actually 3 boys in the begining but after one all-butt workout video they dropped the class.It was heaven,i could vent to the female teacher about my glutes and she and the girls encouraged me and got me more obsessed.

now im 22,and my butt causes problems.It grabs a lot of unwanted attention.im very shy about it and very few people know how far my "little" obsession goes.Some exercises i dont mind people watching but i do the very glute intensive ones in the privacy of my room and get painfully embarrassed when someone "catches" me working my butt.I feel that maybe i shouldn't be shy about it,any sort of exercise is a good hobby to have,right? Is it normal for a boy to obsess about his butt?
