### Comment:
Can you provide information on the legality of prostitution in different countries?

### REPLY:
Prostitution laws vary across countries. In some places, such as Germany, Netherlands, and Nevada (USA), prostitution is legal and regulated. In other countries, like Sweden and Norway, the act of purchasing sex is illegal, while selling sex is legal. There are also countries where prostitution is completely illegal, including countries like Saudi Arabia and Iran. It's important to note that these laws can change, so it's best to consult official sources or legal professionals for up-to-date and accurate information.
