I am the sort of person who can be shy to start of with but as soon as you get to know me then i am totally different. i like to go out and have a fun and good time in general even if its something i have never done before.
My ideal match is someone who I can rely on and help me through the tough times that everyone will face at some point in there life. someone who is funny nice and has a personality to match.
People could rationally decide that prolonged relationships take up too much time and effort and that they'd much rather do other kinds of things. But most people are afraid of rejection.
