I travel a lot for work and can't see women I've met for months at a time. Texting and phone builds comfort but I normally don't get the same thrill as when I'm there with them; it feels like it's missing an important part. Even when they flirt I don't get the same feeling of excitement I have when I see them; it's a rush looking into someone's eyes or being just physical enough to give them crave being with you. How do you keep sexual tension and intimacy high when you can't see them?
