A good hero has no emotions. Think Keano Reeves in Constantine. He should always speak in a monotone voice, even when he's chasing after the bad guy and his car is about to go carrening off the side of a cliff. He should never break a sweat.
Of course, secretly, he is deeply tormented. But he must never show it! The only person who sees through his monotone facade is his girlfriend, and she will get through to him no matter how vauge and unwilling to talk about his past he is. In fact there should be a long, drawen out sequence where his girlfriend drags the secret out of him. Either that, or something of sentimental value falls out of his wallet, prompting a question that must be anwsered. The tormented hero cannot lie to his beautiful, sexy girlfriend. As mandated by the Gods of the Anti-Guide, the pair must make out and have sex immedately after the intimate confession.
In regards to sex, no one in books ever uses condoms. More over, they never get pregant or have an STD. Heaven forbid your main charecter have AIDS, that would ruin the entire plot!
However, if your charecter does become sick, they must make a mericulous recovery facilitated by their lover's cancer cureing, AIDS vaccinating, lepper healing kiss/tears. And they must always come back from the brink of death, or better yet, come back from death itself after being deceased for a full ten minutes. In real life this would cause irrepreable brain damage. But, of course, you're writing fiction/fantasy. You have a right not to make sense, and there for should never, under any circomstances, use rational logic.
As for near death experiances, your main charecter should either meet a dead reletive (such as their loving mother who was killed in a fire started by your disfunctional aunt because she was always jelous of her sister's virtue and good looks and espically jelous of you for turning out so pretty and having all the boys/girls after you) or meet God/the devil. And, when they come out of their coma, they should say something really cool like, "I told you I'd be back, baby." Then, naturally, they have sex right there on the hospital bed, tubes and all.
