yes totally normal, maybe in your mind you weren't mature enough to have sex until you were 19? im not saying this in a mean way though. im 16 and i dont think im mature enough to even have a relationship. so yeah.
Yes, normal, it will get better in a few years too. Women are taught by society in general not to enjoy sex at a very young age and that's why most feel open talking and practicing sex not until they reach their 30s and sometimes 40s. This is especially true for women who have led a reserved or conservative lifestyle.
