so like me and my bf can have sex nonstop all the time

but like once he mentions anything about working out at the gym I turn into this...

Like i get uncomfortable.... probably cause we'd be at the gym without anyone but each other. (his dad's owns the gym)........ idk if its just me but like I get hella uncomfortable working out with someone I'm crushing on or dating. I know like if youre dating you will experience MULTIPLE AND DAILY FAILS but like im so uncomfortable with working out with my bfs.... I couldn't even do it when i was dating my ex (we dated for over a year but have known each other for 5 years)
