Just from personal experience[I've been there], you should really take time for yourself - grow into yourself, so to speak and be comfortable with who you are, and what life means to you. It is okay to be alone, and not have a boyfriend. If you have concerns about this present relationship, the feeling that it isn't right, than it's not. You shouldn't give the boyfriend the wrong idea, by staying with him. In the long run, you and him will respect the honesty more than the 'experience'.
Fountain of Youth, had awesome advice! Start your adventure, in the end you will respect yourself, others around you and life much more.
Can I ask how old you are? It often has no bearing, I was just wondering.
