Fantastic, this sort of thing can really mess people up. I once told a friend I felt bad because I'm married but had a little bit of a crush on someone, the reply was an assurance that while I'm married I'm not DEAD.
As you say, the thought of consummating is repugnant, but the thought of never having another crush, well that's also horrid. I don't actually have a crush currently, but I do have an incredibly potent ever-growing powerful desire for my beautiful wife, and you know why that's amazing... because we CAN consummate it, it's real. The book 'high-fidelity' covered this area nicely.
