Am I missing out on life?

I'm a rather shy and quiet person who prefers his privacy. Some people even say I'm a hermit. But the reason why I feel like I'm missing out on life is because I hardly go out with my friends or peers to pubs, night clubs or parties. Well, I don't even drink for that matter. But I hear other people talk about how much of a great time they had when they went out or I see loads of photos on Facebook of people drinking and having a good time with their mates and hanging out with hot girls and even going abroad with them. I can be sociable every once in a while but I feel like its not enough. My family want me to get into watching sports because it's a great way of meeting people but I think watching sports is boring and overrated. And two girls once told me that if I didn't become more sociable I wouldn't be able to do anything like have a girlfriend or even get married.
