The others are right, it's a really individual thing, and don't let anyone pressure you into it! I personally love it, and was hesistant at first, but waited until I was sure I was into it. It's better to take your time than to do something you might regret. And if you never do it, that's fine too. There's plenty of other ways to express love...

Good luck, and look after yourself k?
