I grew up in those areas besides west compton and westmont area and yeah the black area are slowly being taken over by mexicans. Really all of LA is being taken over by mexicans; if you plan on moving to LA the best black are to move into is the View Park-Windsor Hills and Ladera Heights area. The dating area for a brother is not bad; you basically have the pick of the litter with the hoes; there's a bytch for you. If your looking for a educated sister, there here; if you want a sisters that into the ratchet shyt, there here. Really it can be hard to stay in a relationship because there are women everywhere in LA. Since you like asian females; for a brother it's not bad depending on the area your in. Long beach and carson; you will see a lot of brothers with asians.
