Hi, so many good pieces of advice on this thread.
But here is my motherly advice for you ............

Appreciate yourself for who you are and stop worrying about what everyone else is doing. If you aren't ready for relationships, great! Watch what is going on around you and learn from that. This way you CAN avoid all that awkward, silly teenage behavior.....as well as alot of hurt that goes with it.

As for feeling inexeperienced, so what. There are plenty of people out there feeling the same way. Heck half the people who say they are doing this or that probably arent anyways. So stop worrying.

Focus on you and your interests and don't let peer pressure control you. In the end, you will be the happier one for it.
