Dating apps tend to focus on big picture stuff like hobbies and TV preferences, but they're not really that important. A relationship can survive if your partner doesn't share your love of rock climbing. It's the little things that can make or break a romance. If you don't share your partner's temperature preferences, for example, it can lead to some pretty big problems down the road. If one of you runs hot and the other runs cold, you're basically dooming yourself to a lifetime of quibbling over climate control. Presumably you'll be spending most of your time with this person, it's best to know whether or not you're in synch from the get go. The same goes for things like cleanliness level, which side of the bed you sleep on, how many alarms you need to wake up and countless other little things you never think about that actually matter.

I don't care how confident you are, everybody has a part of their body that they're embarrassed of. Whether you admit, there always exists a fear that someone you like will see that body part and become instantly repulsed by you. This is ludicrous, of course, but imagine how nice it would be to know from the get-go that your insecurities are unfounded. For this reason, dating apps should include a section where you can upload pictures of everything you hate about your body. People will go in knowing exactly what they're getting into, and you'll rest easy knowing that they're okay with it.

We all have something that is more grating to us than a million nails on a million chalkboards. Unfortunately, these pet peeves aren't always apparent to those around us. The last thing you want is to have the person you're dating push your buttons, especially if that person has no idea of knowing that what they're doing is a no-no. It makes sense that you should have a way to let any potential partner know what pisses you off. That way if they do it, they have only themselves to blame when you choke them to death.

Any relationship worth its salt will eventually involve meeting each other's families, and here's the thing: Everyone's family is insane. Unfortunately for us, we can't choose our relatives. We can, however, choose who we date, and a brief rundown of all the important people in a potential significant other's life would go a long way to helping you make an informed decision.

Granted, a lot of people do put their kinks on their dating profiles, but, generally speaking, these people aren't looking for anything too long-term. More relationship-minded people tend to keep their sexual desires hidden at first because, let's face it,  it feels odd having the first thing your potential future spouse reads about you be "I can only get hard when people suck on my toes." Why though? Sex is a big part of a relationship, and if it's headed anywhere the other person is gonna find out eventually. Might as well be now, right? Imagine how shitty it must feel to break up with someone you like because you find out down the line that the two of you aren't sexually compatible. Also, I don't know about y'all, but I'd much rather find out about someone's kink on a dating profile than by being led into their sex dungeon.
