Yeah non-Muslim Indian guys never, ever go for Pakistani girls. It's just rare, and doesn't happen.
a) some have this stupid nationality beef (to me that's stupid, good pussy is good pussy, regardless of country)
b) some have religious reservations
c) they're scared of your dad
Personally as a male from your side of the border, I don't really care, I'll go for Pakistanis or Indians, but Indian guys definitely have some problems with going for Pakistani girls.
