I lost mine when I was 15 years old. It was a mistake! I thought I loved the guy and it turned out that he was a total loser. I became attached to him for 2 years until I finally realized it was hopeless. Honey, if it's only messing around don't do it. You will probably end up regretting it. Not to be mean or anything, I'm speaking from experience.
It was important to me though, I felt different, definitely. If not to explain it any other way. It was a major turning point in my life. It made me feel more confident. I felt more alive as well. It hurt like hell though! I'd say if you don't think you're ready, then you're not. Just wait until the day when it is a complete decision that you've thought through over and over until yes is the final answer, and you have no second thoughts about it.
Don't do it to make him happy, do it for yourself, if you do.
