Hi, firstly welcome to the forums.
I do understand what you're going through. I'm also in a long distance relationship. My OH is in Canada and I'm in the UK. We see each other at most twice a year, but more than likely it's once a year.
As BV said don't listen to people who say LD doesn't work, because it can work and it does. My OH and I have been together several years now, and I'm not going to lie and say it's easy because it's not but I am far happier with him than I have ever been in another relationship.
We have our own lives and we spend as much time as possible with each other, the main thing that we need is Skype it is essential, as we can talk as much as we want, and can cam up and look at each other. The other thing we use is What's App. I've also found this invaluable as it means we can text each other and send each other voice clips and pictures for free.
We make sure we make time for each other, not just for sex haha but for everything. He usually works nights during the week, there's a 5hr time difference between us, with me being 5 hours ahead. We talk briefly throughout the week on Skype, generally this can range from an hour depening on what we're both doing more more often than not Monday - Friday it can be less than 30minutes each day. But it's better than nothing. This is where WhatsApp comes in, because just because we're not actually talking we're still texting each other throughout the night. Our day is Saturday as he doesn't work, I'm generally not working and when my terrorist is in bed that's when we spend our time together. We call it date night. This usually comprises of us playing games together, We'll play different games like Battleship (He has one half of the set, I have the other) we play online games like FPS, MMO's we're usually on Skype for all of this so we're talking and having a laugh together. And then we watch a movie together. We'll pick a movie cam up on Skype and 1-2-3 Press play, and we'll watch the movie together whilst eating and chatting. It just feels like we're watching the movie together.
Intimicacy wise, I've not found a sex toy that actually works in regards to the ones specifically designed for LD relationships. It just caused a lot of frustration when they wouldn't work properly ext. But what we do is just good old fashioned Skype sex lol. We just tell each other what we want to be doing to each other, put as much description in it so that we're basically begging for each other. I tell him what I want him to do to himself. I got him a male masterbator so that it's something from me he can use. He's also purchased toys for me, so he'll tell me what toy to use, what he wants me to do to myself and that's more than enough for us until we're together. We'll also tease each other, I'll send him some naughtyish pics and voice clips some Sexts to tease him a little until we have our date night and have time alone.
I hope this helps, I know not everything we do will be what everyone else wants to do. But we have a great relationship, a strong bond that just gets stronger with every passing month.
