ฉัน chán "I" (if you're a woman or anyone comfortable using a technically neutral pronoun that's overwhelmingly used by women, otherwise ผม póm)

ฉันไบเซ็กส์ชวล

chán bai-sèk-chuwan
"I'm bisexual."
(I actually am)

fun fact:

note the ์ above the letter ส, which makes the "s" sound. the symbol is called การันต์ gaaran, and is used in spelling loanwords to silence letters (usually syllable-ending ones) that are are not pronounced in Thai, to maintain the original form.
