Never having lived anywhere with an especially large Mexican population, I'm sure most of the "Mexican" girls I've seen were Salvadorian, Honduran, Venezuelan, Colombian, etc. (although my brother did have a pretty 13 year old half Mexican/half Irish girlfriend who I thought looked more like a light skinned Puerto Rican than anything else). Plenty of them are pretty, but I can't say I really have a fetish for any racial/ethnic phenotype or nationality. I will say I tend to like white/Hispanic/Asian/mixed race girls more than pure black or Pacific Islander girls. I guess my main type would be long/lean brunettes with cute/pretty faces and long hair, but it's not a hard and fast rule by any means.
