Androspe, since I'm intact, I would not venture to try to add to Thickjonny's and Big Al's suggestions, which sound eminently sensible and practical to me. I'm chiming in only to say that, as a gay man, I have seen up close a good number of men who share your condition, but who function normally and have no trouble...unless, that is, by "cracks" you mean painful, raw breaks in the skin. (The surface of the glans is, strictly speaking, not skin, but mucus membrane, which nature intended to stay moist...as, for instance, the inside of the mouth. Yours is likely more sensitive than most.) Skin conditions in general vary widely, quite normally, from person to person, extending from one extreme to the other--some naturally moist and supple, some dry and even flaky. (Just take note of the myriad skin-creme commercials on TV!) So if your glans is merely wrinkled, not raw, and causes you no discomfort, I don't think I would let it disturb me...particularly if you heed Thickjonny's and Big Al's suggestions.
