Being a Filpino-American (U.S. born), I definitely have advantage as far as passing. However, I've seen some non-Asian CDers who look like VS models and they're amazingly beautiful. I'm always wishing I had breasts like theirs, but unfortunately Asian women are typically known to have small ones. Oh well.
For me, I'm not as petite (5'5 without heels, approx 165 lbs) as typical Filipino males, but I'm constantly practicing being in femme (i.e. putting on makeup and all) so I'll look well enough to pass (See my profile picture).
Last week, I was browsing around at a Burlington Coat Factory and an SA, who was also Filipino, asked if I was a Filipina.
When I responded back, I said "Si" as in "Yes", in Spanish. I have no idea why I said it that way, I guess I was caught by surprise, but after that I just smiled back and continued to browse. She didn't give me any funny looks or anything and just went back to what she was doing.
I've also had comments from several other GGs that I look completely passable and not only does it make me feel good, but it builds up my confidence knowing that I can go out and blend in.
I've always known that there a lot of Filipinos, in the P.I., who are gay and they're not shy to hide it. In other words, there are those who are flamingly gay and will flaunt it. When I was there back in 1991, me and my friends, were at a club and saw this "Balka" dancing with a gay caucasian. His mannerisms were so flamingly exaggerated that we almost puked when it looked like they were about to kiss. It was a scary sight, but the people around us weren't really surprised.
For me, I'm so totally not gay and crossdressing is as far as I'll go. I have no intentions of doing sex reassignment surgery so I'll leave that to the "Baklas" over there.
