First time Sex

I'm 18. My boyfriend and I have been dating for about 6 months and everything is great. We fool around all the time and give each other orgasms. He's fingered me and I've blown him but we haven't gone all the way yet. Neither of us have ever done it; and we are working out and trying to get in the best shape possible so we can enjoy the experience to the max, and for health reasons as well lol. I'm just wondering if there are any tips as far as what we should work on physically or emotionally to make it the best possible experience. Thanks.
