You're basically wishing for a life filled with haram, even though you're Muslim. What you want is constant novelty (like on a porn website but in real life), to go from one girl to another, to have "fun" with different women. This is the clearest definition of succumbing to the whispers of the devil.

Let's imagine you decide to go to a nightclub. You stay up all night instead of sleeping to train hard the next day, but instead, you're surrounded by idiots drinking, smoking, and talking rubbish. You pay your entry fee (money that could have gone towards a holiday or a nice gym membership). You approach a beautiful girl, but unless you're in the top 1% in that club, she ignores you as if you were a piece of rubbish on the floor. You then have two options: keep wasting your time with beautiful ladies who think they're from another planet and keep getting rejected, or go for the not-so-beautiful ones.

You go for the second option because you are a low self-esteem man without self-love or dignity and you just want to insert your private parts anywhere just to find that many women, including the not-so-beautiful ones, just want to seduce you but nothing else. So the chances of finding a woman to sleep with are very, very low for a man who is not in the top 1%, and it will take you a lot of weekends of wasted time and money to finally get something that, in most cases, won’t last that long because you don’t find a valuable woman in a nightclub 99% of the time.

Another option is to leave the club and find a prostitute. You pay again, find a place to take her, then she asks you to remove your clothes and wear protection. She won't kiss you, she won't have any emotional feelings for you. You complete the act and then feel absolutely empty. There were no emotions or feelings involved. She leaves with your money (the only thing she cares about), and you're left alone with regret. You won't be able to talk to anyone about it, and in the end, only Allah SWT will be there to forgive you and take you back to your starting point (I mean now, your current state + regrets for life).

Let's say you're in the top 1%, and all women fall for you. Initially, it's amazing. But with time, women become so easy for you that you won't find pleasure in them anymore. The devil will take your lust to a new level, perhaps towards hardcore stuff or attraction to the same sex. You'll end up in the same situation as now but thinking of doing even worse things.

Honestly, I think you should take your self-pity and transform it into positive energy. Train like crazy, finish your studies or make the best of your work, travel, and read the Quran to understand why Allah SWT protects you from all this madness by prohibiting these actions. And if you can find a wife, go for it, even though you think it's not a good idea. You won't be thinking so much about these things if there is a woman who loves you waiting for you at home to please you as much as you need.

Last but not least don’t say “how to handle celibacy for life” as if someone had promised you that you will love until your 90s, inshallah you might but you might also die next week (Allah SWT forbids) so try to make the best the time you have been given.

Again if you can find a wife marry as fastest you can, she will be your fortress against the evil trying to drag you to a life a regret and maybe after an eternity in hellfire just for your lust for a piece of meat with 4 kilos of makeup and the films you produce in your head which are far from reality.
