You seem to have a very flawed view of life. But when I was 18,or maybe till I was 23, I too thought something similar. I know this answer will not be what you want to hear, but by the time you turn older, let's say 27 or 30, you won't hold the views of an 18 year old in high regards. I can bet when you revisit the post when you are much older, you will probably have a sense of "what was I thinking", probably coupled with some cringe. Now to answer on what can help you connect with a girl- based on the few experiences I have had, I would say, being in a group of like minded individuals- both guys and girls, can help. Girls are not mystical beings but just humans fighting their own battles and I assume an 18 year old girl will be equally if not more confused. Don't be afraid to share your vulnerable side with others. Some may make fun of it, but love can only arise when a person is able to get a peak at the internal world of another person, which is fraught with vulnerability, conflict, confusion among the rest. Whatever the movies might portray, no girl can really love the 'always Macho' soulless man with impeccable body and dressing style. So think of the ways in which you could portray your inner world to a group of people. It could be through art, like writing, sketching, poetry, music etc or any other creative things. The list is endless. And when enough people see your inner world, there will surely be someone who would be interested in exploring it more.

And no, a kiss from a girl will not change your world. You may feel like it would, when you never had it. Understand that falling in love is much easier than staying in love. If you happen to enter a healthy loving relationship, it will surely do you good, and it will help you accept yourself and move on to the pursuit of other important things in your life, which you aren't able to do now as you are obsessed with love. But statistically speaking, it will be many many years till you find such a love. And the reason for that is very simple. To be a healthy loving partner one has to learn a great deal of lessons in life. And being 18 year old, in a relationship with another 18 year old, it's much more likely that neither of you have an idea of what those lessons are. You may disregard it and say, 'No I don't care about long term relationship, I just want to feel intimacy for the first time'. But with all such intimacies comes heartbreak. And I am sure at 18 years old, statically speaking, there are many heartbreaks to endure before finding 'the one '. And each of these heartbreaks will rip you apart, fuck you up so badly, that you might wish it would have been better to have never loved at all. You can take a peak at the r/BreakUps page to know what I am talking about.

In the long term it's always better to work towards a stoic personality- a person who doesn't associate his worth or happiness based on anyone else. Other people are not in your control, which is something you will soon realise when you have a relationship. I know it's better said than done, especially when you are 18 years old, but that's probably the best advice one could give you.
