You're placing far too much pressure on one persons' shoulders which means there is no balance or harmony in this relationship. I've seen too many relationships go South because somebody has a pink and fuzzy idealized version of what the perfect partner should look like, smell like, dress like, and talk like. This is not reality. If you want a romance novel go to the grocery store and buy as many paperbacks as you can hold. Keep romance the way you keep a garden.
Great sex involves constant tending, nurturing, and caring.
You don't just visit it like a spectator who goes to the zoo when they feel like petting the pretty animals. Emotional commitment is far more important than physical intimacy. Don't jump in too fast. The expression about where fools rush in comes to mind. Again I've got a list of romantic disasters that can all be traced back to a couple who raced into bed together before really getting to know one another.
