Do the math. At over 1000 feet tall, with size increasing according to cold temperatures (which he is capable of inducing himself), that means a flaccid penis length of at least 42 feet and a girth of approximately the same value. Assuming an ultimate tensile strength of 2.8 GPa (and really, it could be much, much higher depending on the orientation of the magic ice crystals composing his penis), one can begin to imagine the incredible amount of pull that Ymir would repeatedly have to apply just to achieve an erection.
Likewise, once an erection was achieved, Doomsday would find himself face with a 140' colossus with compressive strength far, far in excess of the puny 443 GPa (minimum) exhibited by Ymir's member when it is quiescent. Once Ymir's superior leverage, thrust, and sexual technique acquired over a vast immortal lifetime are taken in, I think it is quite obvious that Doomsday is screwed.
