work out clothing

Hello, this is my first post here i am new to this community, and im so happy there’s a support community on here! in the recent years my HS has made itself ✨known✨, it’s in my groin ish area, like where my thighs meet my torso, think like on a doll where the legs connect to its body, right in there. anyway i’m starting to work out and im having soooo much trouble with finding clothing i can even wear without it getting painful or irritated and swollen. i usually can’t wear underwear, i only wear it when im wearing a skirt or something along those lines because it just hurts. (and yes i am on medication for it) but i just have no idea what to wear when i work out, and go swimming but thats for another day. has anyone come across this issue? like i really want to get back into rock climbing and ive always wanted to pole dance but i CAN’T because of the harness and how poke works. im honestly just begging for any recommendations of work out shorts/pants for a young adult woman :(. i appreciate yall for letting me be vulnerable and i hope the community can help me even if its just knowing others are going through this too.
