Here in Malaysia, my ex was very loath to hold hands (never any cheek kissing), sometimes using the hot weather (sweaty hands) as an explanation or just that we're in a homophobic society. But I see young butch femme couples walking around holding hands all the time. Or, walking very close together. (Or having sex in the toilets, but that's another story).
I don't know if it would be different - better or worse - if I were with a white partner or not. Certainly years ago in NZ I had yelling from passing cars, stones thrown, and other fun stuff while with a girlfriend and holding hands.
It was funny being in Korea. I could walk around holding any woman's hand and no one would blink an eyelid because it's culturally acceptable. I would often hold hands or walk arm in arm with my straight mate. But walk around NZ, hand in hand with one of my sisters.
For them it's all about "someone might think we're gay."
Like lots of other people, I'm very affectionate. I'm not fond of tonsil hockey though.
