why does it seam only mexican women are attracted to me?

im a dude of 17 years of age and im a redhead, well i guess not completely a redhead, im not a giner and the red is sorta auburn, brownsish darkish red and have noticed that alot of mexican women that like me, while blacks and whites do not really seem to care, for example, today, and this is true, i was running passes (delivering passes to classes) and in a class a few mexican women started staring at me and one yelled out actually saying “your HOT!” give me your number, and have had sever incidences like that but not much and none with blacks and whites, is it something with the red hair or something!? or is it just myself they like or something?
by the way im white
by the way, im not a stud or anything since im 6’1 and am 205 pounds so a slight overweight
