Either way it's going to suck, I just don't know what the best option would be. Option A, I could get sex out of the way with someone who's willing to teach me and make it a nice experience; B) continue to date him without having sex (intercourse) until he leaves but stick around for the intimacy and the other stuff; or C) I cut him off and end it.

Two very fundamental question: Do you love him? Does he loves you?
If yes, then Are both of you willing to wait for each other. A year may appear long, but will pass in the blink of an eye. (The catch: someone comes by and the promise to wait is destroyed.)
(I hate to see a good relationship broken just because of work. Hence I hope you can consider the above questions seriously.)
With regards to sex, no (other Opinions had given the reasons).
With regards to intimacy, reduce or remove it immediately (parting will cause you to missed that intimacy, which will tempt you or him to go for a quick relief)
Part and end it if there is love is not strong enough for both of you to wait for each other. (Where you both agrees that there will be someone whom you could love "just around the corner" after you parted.)
