What's it with Indian men and Foreign women?

Another foreign tourist- this time a Japanese woman, has been raped in Rajasthan. What's with this spike in sexual assault against foreigners? Could it be a case of someone trying to enact a scene from a "Hot Asians" Porno? Have sections of Indian men started thinking of foreign women as experts in the sexual acrobatics depicted in imported smut?

I know one guy who keeps going to Goa for the sole purpose of ahem "enjoying the company" of foreign women. I still wonder why people tend to give foreign mediocrity preference over local excellence. Everywhere you see- a guy with an imported girlfriend will get treatment like a superstar! Can someone explain this?
