This began as a response to another post but turned out to be way too long and goes into far more than the OP of that thread intended, so here it is to stand on its own.
Filling in your profile on a site like this is important for several reasons. It shows that you're willing to put forth the same effort that others have. It tells people something about who you are, not only in what you say, but also in what you don't say. What you share lets them know what you're interested in and what your expectations are, while what you don't share indicates a bit of what you're either insecure about, want to hide, or don't find important.
If your profile is completely empty it doesn't just say that you're too lazy to fill it in. An empty profile says that you aren't willing to make any effort at all. You are just here to take and not give. It also says that if you find nothing important enough to share, then you're not interested in learning anything about what other people think is important. You're just in it for the physical and then you're done. That's not good for any kind of relationship and will drive people away. For a healthy relationship (friendship, romance, cuddle buddy, etc.) you must not only be willing to share and accept what the other person is willing to give, but be happy to do so. It is from this mutual sharing that the benefits of relationships grow. That is what creates connections between people.
Part of what drives people into this kind of mindset of focusing only on the physical with minimal effort elsewhere is, I think, desperation and insecurity. People lose hope of finding meaningful connections and let go of attempts to do so in the idea that settling for less might make it more likely to get at least something of what they need. They've been rejected so many times that they don't want to put effor and hope into yet another. I know from experience that that is a hard place to be in, but giving up on meaning will prevent you from ever being fulfilled. But desperation, loneliness, and insecurity are not necessarily core problems in themselves; they may just be symptoms of a deeper problem.
If you're lonely and desperate, take a look at yourself and find out if there is something that needs to be addressed. Look for things in you or in your life that are begging for attention and need to grow or be let go of. Seeing a professional counselor can help greatly with this. But don't expect them to make things better for you. You have to be the one willing to take guidance and do all of the hard, hard work. It can take months or years to work through things that you don't even know are plaguing you, so don't get in a hurry. Going through the long struggle may be exactly what you need to get better.
I first got on this site about a year ago very lonely after a breakup and feeling very insecure about myself. After months of depression and months of not finding any cuddle partners or even getting any replies to my messages, months of counseling and time in the hospital and getting help of other kinds, I was finally able to think clearly enough to sort through things and figured out that my depression and loneliness stemmed from insecurity, and my insecurity stemmed from a lack of trust that God knows what I am good for. I never could live up to my own expectations of who I thought I should be and always felt like I was not good enough: not good enough for the woman I loved, not good enough to be loved, not good enough as a Christian, not good enough as a student, not good enough as an employee, not good enough as a son and brother, and generally not good enough as a person. I was insecure for my entire life up to that point, and it was that insecurity that caused me so much pain and drove people away. In finally realizing that God knows all of my flaws and weaknesses and still chooses me for his plans in everything about my life, I found the confidence to accept that I am good enough. Nobody is a better judge of character and of worthiness than God, and if he still gives me things to do and people to be with, then I am the best person for those things despite my imperfections (and possibly even because of my imperfections.)
In gaining the confidence that comes from trusting God's judgement of me, I found healing of the insecurities that caused my loneliness and depression. And surprisingly, I began to get replies to messages that I'd sent out months before. Sometimes God puts us through hard things -- even torturously painful things -- because that is what we need to grow. If I'd found a cuddle buddy during my depression it would likely have helped relieve some of the pain I was going through, but I think it would also have been likely to have become an opportunity to become desperately dependent on them to keep that pain away and prevent me from actually healing. Don't use this site as your only source of hope for satisfying your needs since you might not know what you really need. But also don't give up on it as just another failure if you don't get replies or cuddles. Just put in a little effort to make yourself available as a person and let it be an open opportunity for connections.
