Depends on what religion you turn to. You could turn to one with strictures on sex. Also, it's not just practice at the mechanics of sex, but being able to communicate with any and all of your partners that makes you really good at what you do. I don't give a stellar blowjob because I've got a lot of practice bobbing my head up and down - it's because I pay attention to every minute thing I can possible pay attention to about my guy leading up to and during it, as well as asking questions.
And many old-fashioned people or people with vague religious inclinations have a problem talking about sex.
