Is it wrong that i am sleeping with my girlfriend but no at 17?(10 points for best answer)?

I think your question is very mature. I think it's wonderful and true insight into your character. Good for you for being there for her without any other expectations. I do think 17 is too young to have , you guys sound like you have a wonderful basis for a true relationship that can lead into a strong marriage. I hope the best for both of you.
