Where is it legal to pay for sex?
<|assistant|>
It is generally illegal to purchase sexual services in most countries. However, there are some parts of the world, such as some countries in South America and some places in Asia, where it is legal to pay for sex. Additionally, some countries have laws allowing for the prosecution of clients but not prostitutes, creating a grey area in terms of the legality of paying for sex.
