My first time was wonderful. He spent the time to help me feel relaxed and comfortable, and I trusted him. He also knew to spend the time to get me well lubricated--he just used his saliva.
My first time wasn't so bad. The guy knew how to "warm me up" and open me up a bit before moving straight to intercourse. But friends of mine have had completely different experiences. The younger the were when they started, the worst that first time was.
