Casual sex with fuck buddies can be very scary and very stressful. Things are not always as they seem. I have tried this process, to meet a companion. You can meet a lot of interesting people this way though. You must be cautious, because people do not always look like their photo, and they are not always who they say they are. It is very easy to write a profile about who you want people to think you are, or perhaps maybe even who you think you are, but it often times is not exactly as it appears. You can meet some fun and interesting people on online dating sites, that you would not have been able to meet otherwise. So it can turn out either way, fun and interesting, or bad and fake. You will just have to give it a chance and see which one you will get. Typically you have made a new friend.
