Thats tough and I’m going to be in the same situation over the summer, and there isn’t a lot you can do. But I would say try telling him in a simple text how much you want him. Most guys love it so he probably would to. You don’t need photos of skype or anything, but simple words and text messages can be pretty hot. Although they can make you want him even more aha. I think you should just go for it one day and surprise him with a really hot text telling him how much you want him. I bet he’ll love it and hopefully will reply with something just as sexy. Be daring and make the first move and hopefully he’ll play along. With ldr all you can really do is use imagination otherwise.
