I understand the painful and boring part, because I think some young men aren't in tune with the needs and desires of young women. The painful part comes from attempting intercourse when a woman's not yet ready, whereas for a considerate lover, ensuring a woman is ready for intercourse is the best part! There is a lot of information available about good sex, so I suggest you and your partner read online, or buy some good books, and then practice what you learn. Then it should be good or great, although maybe not the first time. In any case, being informed and practicing is an enjoyable journey, which starts good and gets better.
