First tip is don't give out your real name on a public forum.
You need to be very careful with your identity in Peru. Remember you're now in a country with widespread poverty and crime is rampant. Any gringo is automatically a special target of interest and a woman especially so.
I recommend you edit your first post to delete your email address which gives out your last name, and then modify your FB privacy settings so the public can't see your photos or personal info (I just checked to see if I could look you up on FB and... yep!). People on the forum can reach you via private message and don't need your email address so don't post it.
I don't want to overly scare you, but unfortunately you should assume that any Peruvian you come across will try to screw you over until proven otherwise. You need to boost your paranoid setting just a bit... because it isn't paranoia if they're really out to get you
Be smart, be careful, assume that people here are trying to take advantage of you (because they probably are). There are really fantastic good people here too, but you need to get to know people really well before you lower your guard.
