I lived in Dubai for some years and traveled extensively thru the Gulf region. Just keep your affection out of the public eye and you will be fine. If you hire someone from an ad, be sure to meet them in a public place like coffee shop etc and don't talk about sex. If you like them ask if you can hire them to show you around the city. If they come to your room do not get any money out until after the sex. Dubai, Abu Dhabi, Doha and Bahrain are basically similar to being in London. I would not do anything in Saudi or Kuwait.
