You didn't have enough motivation to barge into the castle and possibly get slain or taken to prison just for a mare or two. True, extraordinary mares, but still. You trudged back to Ponyville, where once again stares were a second-long and you were recognized. You felt more at home here than any other place, so why leave it for that over-regal Canterlot, anyways? The hard-working atmosphere of Ponyville reminded you of home on Earth - whether that is good or not depends.
So you set to work on talking to ponies, to get a one-night stand or some kissing or anything, because honestly, after so much waiting you really just needed some sort of outlet.
First, Lyra, then Bon Bon, then Applejack - who kicked you once she realized what you were doing - then Pinkie Pie, and so many more your head spun. But, none of them wanted any sort of relationship. Every one of the ponies of Ponyville either had too much to do or they were not interested. Friendship seemed the closest you were going to get unless you left Ponyville. So what could you possibly do?
What to do, what to do...
