inexperienced

hi guys, i’m a 16 year old girl who is beginning to get into my first proper relationship. i’m not trying to jump into sex and lose my virginity the minute we make things official but as a teenage girl, i want this to last and i want to be able to be sexually active at some point during this relationship if the other feels comfortable and ready. i believe that i’m ready and mature enough to take this step in my life but i’m really nervous. i’m afraid of everything from not being good at making out to oral to sex itself. i’m afraid that my nerves will get the best of me and i’ll just be a mess and i’ll drive guys away from me. if anyone can help me or share experiences or stories, it would be greatly appreciated and help me realize that i really am not alone and anyway to make this less of a train wreck and more enjoyable for me.
