>>11820476WTF are you talking about, you could have a woman like picrelated for 10.000₽ (about $160 I think). But if you are caught you pay a 2.500₽ fine (about $40).
Getting involved in prostitution isn't bad because "muh finances", it's bad because it's just sad for everyone around. It's bad for women, it's bad for men, the people involved are sketchy, avoid it.
Also, be aware that "going international" will make you a target, especially if you go to a comparatively-poor country and don't speak the language or are an obvious foreigner due to appearance (a white dude in Mumbai, for example).
