My boyfriend and i are really close and we both want to do it. but there's a part of me that's scared. what will it be like?

Waiting may be right: Congratulations on finding one another. Call me old-fashioned, but i'm not the only person who thinks that the best might be worth saving for the wedding night. Maybe there is something else other than intercourse that the two of you can try. The key is maintaining your relationship -- it takes much work even when you are in love. Best wishes to you both.
