Celticden you do have a very negative view on life. Sex is a perfectly normal part of life and if for what ever reason you feel the need for it, but don't want to upset someone else, lie or make false promises to them in order to have it when you want it, without or the hassle of finding someone who you are attracted to in the real world, is makes perfect sense to find someone you are attracted to this way, pay them the money, have the fun and then carry on with the rest of your life where it left off.
Why on earth does it have to be about 'desperation' or something being wrong?
Maybe look at things in a more positive light and things will start to feel more positive for yourself?
your probably right kate maybe all these work shifts are screwing me up basically i want a girlfriend haha
