I am an American female going to Northeast Brazil for 2 months this summer. I have a boyfriend, but my friends keep insisting that I will be hit on (I can't tell if they're joking). Just for reference, I am 21 years old, quite tall, normal body type, with blonde hair and blue eyes. Are they just messing with me or is this actually a thing? If it is, will telling them about my boyfriend make them go away?
