Pre-Climax Climax/Playing With

Basic Trope: Two characters - usually of the Everyone Can See It type - have sex before a climactic event.
 * Straight: The night before the Five-Man Band goes after Emperor Evulz, Alice and Bob decide to have sex.
 * Exaggerated: Every couple - from main to beta - has sex before the battle.
 * Alice and Bob have sex before every major battle.
 * Downplayed: Before the final battle, Alice and Bob finally kiss.
 * Justified: Alice and Bob always liked each other, and they might not make it back, so...
 * Inverted: Glad to Be Alive Sex
 * Alice and Bob, a normally sexually-active couple, abstain the night before the big battle.
 * Subverted: Alice goes alone into Bob's room. It turns out they're just talking about the strategy before the big battle.
 * Double Subverted: ...Then Bob says "you know, I've always liked you, and we don't know if we'll make it back..."
 * Parodied: Anytime Alice and Bob are separated - going to the grocery store, for instance - they have wild sex just in case one of them doesn't make it.
 * Zig Zagged: Alice goes into Bob's room...to talk about training. Bob suggests they sleep together, just in case. Alice rebuffs him, but hints that after the battle, if they both make it, she might be open to the idea...
 * Averted: No one has sex before a big battle.
 * Enforced: "This story needs a couple of steamy scenes to really hook in the viewers." "How about we have Alice and Bob do it before the big finale?"
 * Lampshaded: "Imminent disaster makes me randy..."
 * Invoked: Bob talks about his long dry spell and the fact that he might not be able to remedy it around Alice.
 * Exploited: Bob is a rapist who relies on manipulating his victims into bed, so he uses the upcoming battle to seduce Alice.
 * Defied: "You want me to do what? Hell no! I don't care if there's a battle tomorrow!"
 * Discussed: "Boy, those Action Girl types are easy pickings right before a big battle!"
 * Conversed: ???
 * Deconstructed: Alice and Bob have sex, and both survive the battle. Cue massive So What Do We Do Now? regarding their relationship.
 * Bob impregnates Alice. After the battle ends, they're stuck with a child to support.
 * Reconstructed: Later, Alice and Bob's relationship has gotten boring, but this spices things up again.
