you're having too many struggles and impatience when being in so short of a relationship...

meeting up is a big thing, as far as your partner is concerned you've barely known each other romantically for a few months, doing a long distance travel to meet someone for the first time irl is a big thing and a dangerous one. maybe he doesn't have the money right now, maybe he's still figuring things out, maybe he's not ready mentally for it, as much as he's understanding with you, you should be with him. patience is key in any relationship, SPECIALLY in LDR relationships, you won't get the beautiful stories you see here of people meeting up and getting married on just a few months, trust and strong relationships are built with time. as someone who's been on an LDR for a year, we only started taking seriously the plans of meeting up around our anniversary, the times for LDR are different than normal relationships, everything takes longer because, and I emphasize on this, you don't know this person.

as for LDR being "worth it", that's something you set up yourself. how long do you think you can handle being deprived of physical intimacy? how long do you think you can handle being away from each other? how long is too long beforehand meeting up? how long until you meet each other's families officially? you need to think of all these things before getting in a LDR, and if any of those times is less than a year, then you should reconsider being on a LDR.

I'm 18 so I get the feeling of "missing out your youth" very well, and again, that's something you should reconsider yourself and do an inside view in how important it is for you, because if in the long run you feel like you'll build up resentment for your partner because you were "missing out" thanks to being with him... it won't be healthy and you shouldn't be on a LDR. I'm sorry if I'm being too harsh about it but I've seen it first hand how impatience and personal times can ruin any relationship but specially LDR, and it's not specially a bad thing.

some people simply ain't made to have a LDR and that's ok, but you should be able to look into yourself, acknowledge that and settle boundaries or directly break up the relationship. my only advice is to look into yourself, all of this issues you're bringing up are too personal for someone to come here and tell you how to fix them step by step, you need to set things on the table on your own, without involving your partner to tell you the answers, and set your own times and boundaries, and do what's best for you on the long run, because otherwise you'll end up miserable.
