My significant other lives 1600 miles away and we've been together for almost 2 years. He's a musician so since we met it was always a couple months together in the same state and then long distance for a few months while he tours. Now he lives in OUR house over in NC (his hometown) while I'm hanging out with the folks in CO (my hometown) temporarily while I seek support/help for my bipolar.
It's hard when you are apart from your special someone.
But trust me, you will find ways to keep the sexual flames going.
