Getting hit on in the gym vs everywhere else

Okay lady's so i cant be the only one! Im in college and i go to our gym on campus. Now im there to workout and i mean business, no one has time to be sweating makeup everywhere! My hair isnt done to impress and lets face it i just look like a prepubescent boy (short hair doesnt help much). Im not shy my body is pretty damn good and i get glances. But ever notice how some guy whos alway there and glances at you every once a while maybe says hi (but because of proper gym etiquette doesnt flirt while your working out) comes up to you later when your all dolled up looking good and tries to flirt and has no idea who you are and you only ever see them every time you workout😒. Like really ... This is what i look like 10% of the time, the gym look is the other 90% (minus the sweating)
