When someone does not know what they are doing it's difficult to be "comfortable". This explains why the "first time" many people have sex it does not live up to the "hype". I would imagine this is even more so for girls/women. Not many start out the gate having powerful orgasms. If they were with a young man or boy with very little experience odds are it was probably over with before she knew it. Most likely there was little if any foreplay involved.
Having great sex requires practice and knowing what excites you as well as your partner. You have to (want) to be good at it.
Was it worth it? Of course it was! Very few people have (dying as a virgin) on their "wish list". LOL! Seriously romantically one looks forward to "being one" with the person they are in love with. If you desire to have children of your own sex is also way more fun then in vitro fertilization.
