Anyone here dating or writing a Mexican lady?

I recently returned from a trip to Ukraine, talk about GORGEOUS Ladies in the very sense of the word ladies. However they simply do NOT have the same "heat" Latinas have. I'm half Latino so I guess their "cold" nature sort of puzzled me. Anyways I currently am seeing a VERY attractive 19 year old Mexican girl from Monterrey who is now living here in the US. She is very nice & honestly I never thought about having a relationship with her however things are going VERY good between us & I'm thinking about getting serious with her QUICK if things don't work out with my Ukrainian lady. I seem to here a lot about Colomibans & Brazilians but VERY little about Mexicans. IS there a reason for this? Just VERY curious. By the way I'm 34 years old & divorced so being able to land a 19 year old HERE is pretty strange for me due to culture so she is a PLEASANT surprise. I guess sometimes you DON'T have to look too far.
