Im currently single myself, thankfully, cos I need the breathing space for a while. Between the ages of 16 and 22, I was in a relationship, but with three different people! I'd leave one relationship and wouldnt have chance to get my head together before entering another one! Im now 23 and have been single for over a year and Im not really looking, never really have done, people seem to find me.
When you get used to them, relationships are fun, especially if you and that person connect, but they are also hard work, but then apparently thats the whole fun of them! Hope this helps, however I wouldnt encourage you to jump in and out of relationships like I have in the past. It isn't a good idea, and thats all Im going to say!
