Oooh, man this is certainly a bad situation. Looks like you let your pecker pick a peck of trouble.
Lay low, always be with friends, the carrying around a cane might be a good idea...but things can ALWAYS be taken and used against you. Honestly? I'd freaking move. Youre not on your home turf, youre an outsider. You know you didnt really do anything wrong, but people arent going to really care, they will just paint it as youre some randomass foreigner who banged one of Taiwan's own. Honestly, in that instance, I feel like any genuine sanity or reason goes out the window.
Back in homecountry whereveritmightbe, dont you think your men end up getting rather riled about "Them foreigners takin' our womens and our jobs?" I think its just a deep seated notion, no one is gonna be on your side in this case. I would just move.
And really, the deed is done so I'm not yelling at you here, OP, but as a general statement...I know there are some really hot Taiwanese women running around and normally people dont get into too much trouble with their sexual endevours and the like...but man, seriously, this is a culture that you may be not a part of, sex is such a serious topic, and women "losing face", their pride, dignity, rumors about them...bad shit can happen. They can get into a lot of trouble themselves or they can just get their feelings hurt and they will ALWAYS ALWAYS have the upper hand on you. This is their town, and if you piss them off honestly you can be shit outta luck. I'm sure its fun to chase tail but youre on foreign turf here, you never know what youre gonna catch, you dont have the sensitivity to the cultural nuances that you have in your own country. Honestly, you just arent wired to pick up the signals and the messages because you not only dont speak the language, but even if you do speak Mandarin, you dont speak *the language*. You meet a girl back home, youre not just talking to her and learning about her based on what she says...theres something totally mental going on, you read people. Here, its much harder nay impossible to do unless you really really know the culture. So she could be a TOTAL nut, and honestly, how are you really gonna know? Or she could be actually saying something and you might be thinking shes saying something else...and there you go. Problems. I would spend copious amounts of time getting to really know girls and not making any serious moves if you wanna date natives...because honestly, how are people gonna see it? I feel like the natives are just gonna see you as some white (or just foreign) dog who's trying to get with their women. Then, youre f*****, and not pleasantly.
