In short, I've noticed that some people's desires for a partner don't at all match up to the kind of person they are. Whether it's former players going after virgins or the morbidly obese aiming for gym rats, I think expectations should be tempered by an accurate reflection on one's self. The following list is not exhaustive. There are many other categories of considerations to ponder when selecting your potential mate:
1. Domestic Activities (Cooking, Cleaning, etc.)
Can you cook? Do you require that your partner cooks? If your answers to the previous two questions were not identical, then you have unrealistic expectations. You don't need to be Chef Boyardee, just be able to cook some spaghetti before expecting your girl/man to cook you a feast. If both of you guys eat ramen and eat out everyday, cool.
If you're sitting on your couch absorbing the entire Netflix collection on a regular basis, don't expect to be with someone who skydives, goes bear hunting, and lives like Otto on Rocket Power (and vice versa). One of you will be holding the other back.
You broke? You better get used to broke people then because they will be tickling your fancy most often. Bettering your financial situation is a beautiful goal, but expecting your partner to have a wealthy income when you're a few steps away from poverty is wishful thinking.
4. Sex Prowess
You want that girl that can ride it like a rodeo show? You want that man who can lay it down like snakes on a plane? Most people do. However, if you're the type of person to lie there doing nothing while expecting glorious sex, then the person riding you or dicking you down will quickly reconsider their life decisions.
5. Physical Beauty
I'm not talking about whether you're hot. I'm talking about gross mismatches. For example, if you eat junk food regularly, brake the scale, never work out and have terrible complexion, don't expect to be with a vegan who hits the gym everyday and has immaculate hygiene. In my experiences, having a morbidly obese person come up to you with anticipation in their eyes after just having finished a good week at the gym is an unfortunate compliment.
There will always be exceptions to this (non-exhaustive) list. For example, you may be struggling financially, happen to come across that person who doesn't care about your poverty and wants to support you. Your status may be so high that it doesn't matter how shitty you are otherwise. Likewise, you may come across a person who genuinely enjoys cooking for you, is turned on by contrast, etc. My point is that to expect qualities that you in no way possess is quite unreasonable. Moreover, your search for love will be that much harder. Make it easy on yourself and be what you want in a partner. Love ain't magnetism; like attracts like.
