Like accha replied, it most likely will not end well for you; I'd imagine the exact consequences vary with each different situation; such as a married couple getting caught Vs an unmarried or a gay couple; but yes, getting caught in intimate situations in public in Qatar is no fun and common sense would tell one to just save it for behind closed doors :-)

Accha: haha I'm a little disappointed that you as a boy think it's possible to ever be fully satisfied; its not a want and rather it's a God given need like food and water; just like one can never have enough shawarmas, biryani and BBQ grills; love too with all its delights is never enough my friend, never ;-)
