How to get guys to stop hitting on me!?

okai don't get me wrong, i'm not lesbian or anything and i do like it SOMETIME but theres a problem. today was completely out of hand! the dirty flirting used to make me very uncomfortable but now i kinda got used to it but I was with my MOM this time! I'm kinda glad she was there though cus if she wasn't i no some of them might approach. my mom was lik,"did u c the was those *********** stare at u??" I mean, they were really staring and laughing and one of them took out his phone and try to take a pic and well... u no the rest. I guess she never knew some of them went pass the staring and she freaked. i thought she knew though but now she won't let me even go out now because she thinks ima giv in to one of those type one day. i don't dress very revealing and i never encourage them. i just tell them politely to stop and well if they did i wouldn't be on here today. I don't like those type and she just doesn't understand that. she hid all my cloth that's tight and hugs my curves so i dnt feel fat (not revealing) and hid my makeups (that i wear only on special days) and so much more. please help. i don't want to wear a sign behind my back that says stop flirting. (if my mom's there lol) cus i just hate the dirty one
