Accidental Pervert/Playing With

Basic Trope: A character accidentally gets into sexual situations, but always by accident.
 * Straight: Bob trips and falls on top of Alice, pinning her to the ground with both hands on her boobs.
 * Exaggerated: Every time Bob does...anything...it results in him walking in on a naked girl, touching her inappropriately, or, at least, saying something sexual in nature.
 * Downplayed: Bob brushes up against a couple of girls while getting on the train.
 * Justified:
 * Bob is very meek, so girls generally lower their guard while around him.
 * After he was caught peeping as a teen, Bob was hit with a Gypsy Curse and now things keep happening that make everyone think he's a perv.
 * Alice actually likes Bob, but realizes he's too shy to be courted up front. She makes it look like it's accidental, but this is really just to get Bob to ease up around her.
 * Inverted:
 * Alice trips and grabs at something to keep from hitting the ground. This happens to be Bob's pants, leaving him half-naked in front of Alice.
 * Alternatively: while Alice and Bob are making out they trip and fall and a bystander thinks they're fighting.
 * Subverted: The hero trips and falls on top of Alice, but Alice manages to sidestep him...
 * Double Subverted: ...resulting in his hitting his head on the pavement. The disoriented Bob then gropes at some support to stand up. Thanks for The Mammary.
 * Parodied: Bob trips and falls, and grabs at something to keep from hitting the ground, which turns out to be someone's pants...Arnold. And he likes it.
 * Deconstructed:
 * Bob's repressed sexuality results in his subconscious putting him in sexual situations he believes to be an accident.
 * Alternatively, when it happens, he feels so guilty he tries not to look at any of the girls he lives near or is friends with for fear of nearly saying something sexual and feeling bad afterwards.
 * Reconstructed: Alice is a genuine pervert, and Bob scores. End of problem.
 * Zig Zagged: Bob trips and falls on Alice. Alice gets angry and pushes Bob off of her, but their belt buckles are stuck together, so when Bob rolls onto his back he takes Alice with him, and next thing you know she's on top of him. As they are trying frantically to get free, and making lots of unintentionally sexual-looking movements, Bob's girlfriend Carol walks in on them. After explaining that it's not what it looks like and finally getting free, Alice runs out of the room, mortified. Meanwhile, Carol finds herself pretty turned on by the display and jumps Bob's bones right there.
 * Averted:
 * Bob trips, but does not touch any girl at all as a result.
 * Bob really is a pervert.
 * Enforced: Two words; Fan Service.
 * Lampshaded: "Bob, you are such a pervert! And don't tell me it was an accident, that excuse only works so many times!"
 * Invoked:
 * Bob notices an opportunity to trip in front of a girl, and decides to take it so that he can touch, or see, or something. Works, but everyone can tell it's not an accident.
 * The girls are actually trying to get Bob to touch them.
 * Defied: Bob (thinking): "I've gotta be careful; wouldn't wanna trip and accidentally grope one of these girls!"
 * Discussed: "Wow, I'm running down a hall about to turn a corner. If this were an Anime, I would be running right into a pair of breasts."
 * Conversed: "The hero of this series seems to accidentally get into perverted situations quite often. Is it really accidental?"
 * Played For Laughs: By nature of the trope, it usually is.
 * Played For Drama: Alice, Bob's love interest, not only believes him to be a genuine pervert but vows never to forgive him.
