I used to have those issues several years ago, until I stopped handing out my phone number. I can count on one hand how many ladies have my number now, because that's about as many as you can fully trust LOL
Sorry you are going through this. Maybe change your number and only give it out to the gents who come see you. Screen with the ladies through PM or email.
You know what they say: mo' ladies, mo' problems
(or something like that haha)
