I'm a 20 year old gay guy and I'm still a virgin...What's wrong with this picture?

There is nothing wrong with the picture, you just havent led the sort of life which makes it easy to find relationships. This will probably all change once you get into your new school and develop a whole new social life where it will be easier to meet other gay guys without hanging about in clubs waiting for skeezy dudes to hit on you. As you say, you're not interested in having for the sake of it, so there was no point in having casual meaningless , and there are plenty of guys who will appreciate your attitude. There is a LGBT section in Yahoo Answers where you can ask more questions if you want, under Society and Culture, and then Cultures and Groups.
