Race + Romance

I was eating with Girl A and Girl B (both from South Asian American backgrounds) at the reception of a recent culture show. A group of people walked by--- two South Asian American girls in arms linked with their boyfriends, surrounded by some of their other friends. Girl A looked up and waved at the girls with boyfriends, and after the group had left the room, Girl A turned to Girl B and said, "I wish I had a white boyfriend!" Girl B nodded in agreement and said, "Mhhm!" In that moment I didn't think to ask Girl A to elaborate on her remark, but looking back on it, I really wonder what she would have said if I asked why. What makes white boyfriends more desirable than any other kind of boyfriend? Her remark surprised me, but I can't really explain why it gave me a weird/funny/unsettling(?) feeling.
