When Bella sits next to Edward Cullen in biology class on her first day of school, Edward seems utterly repulsed. Edward is stunningly attractive, and inhumanly beautiful, yet he is an outsider too. He moves as far away from her as possible. He even attempts to change his schedule to avoid her, which leaves Bella completely puzzled about his attitude towards her. Shortly after he disappears for a while, Edward begins to talk to Bella, having seemingly forgotten their unfriendly first encounter. One day, Bella looks at Edward, who is far away, in the parking lot. Oblivious to her, a student (Tyler Crowley) had lost control of his vehicle, and it was rapidly progressing in her direction. Bella realizes this at the last moment, thinking she is dead. However, Edward appears and stops the oncoming car completely with one hand, leaving a dent, and shocking Bella with his speed and strength.

If that's what you were asking. If you were talking about making love after they were married it pretty much happend like anyone else except when she was human he had to be extra careful and wasn't as quite "enjoyable" until after she was a vampire and he could no longer hurt her by accident.
