Losing my virginity? Help a girl out!

Nicole
So me and my boyfriend have been dating a little over a year now. We have a long distance relationship so we only get to see each other every so often... We've talked about sex but I think I'm finally ready. He is too he's just been waiting for me. What's gonna help me the most? Best first time position? Any do's and not do's? Anything at all will be a huge help! Thank you!
