What he think about nyah?

I just have a chit chat with my straight friend from the same company, then goes to chat about sex, and he told me last month he was slept with one china girl and pay her more than two hundred ringgit just for 20 minutes, then regret doing it because of money he was spent. I told him, next time if you feel horny you don't have to spend so much money, just get a 'nyah' to give you a blow job for free, the feeling will be the same or maybe much better. But he replied, "klu 'nyah' dah lama aku tendang sampai mati!", erghkk?!
