A Jynx pretty much only uses their lips while making out. This means you'll get smooched a ton, but the action will never really get that hot. If you're looking for tongue though, you might receive a Lick here or there, but it won't be that sexy or effective.
Every time you make out with a Lickitung they'll definitely overpower you with their tongue. Sure, a little bit of tongue is good, but too much will make you feel uncomfortable. This is especially true once you realize their tongue's over 12-feet long and can physically pick you up.
A nibble here or there while kissing is the trademark move of a Raticate. Even though biting can be hot, it's important to note that these kissers can use Hyper Fang at any given time which will really do some damage. That means cuts and hickeys galore... well, unless you're a Rock Type.
If you're kissing a person who's sloppy, wet, and has a water cannon then you're hooking up with a Blastoise - a Blastoise who's usually drunk.
While making out with a Machamp you'll realize pretty fast that they care more about other parts of your body than your lips. Of course it's nice to feel the embrace of your make-out partner, but there's a big difference between being held and being on the receiving end of 500 gropes per second.
If their eyes are wide open while kissing then they're clearly an Espurr who's a Level 100 weirdo. And yes, anyone who's going to stare at you while their lips are pressed against yours is a Level 100 weirdo.
Kissing a Pikachu will immediately produce sparks. It's always shocking when you hook up with a person who you like this much, but hopefully when you do: they choose you (and you guys can make out a lot)!
This kisser's like a Lickitung, but is a way worse kisser... and they know Rollout.
