There are some pagan gods who did have sex with mortals, mostly though in the Greek mythos. Roman possibly also, but outside that I don't think there are many myths of a god 'having sex' with a mortal. Usually it's by really unusual means, or it's between a god and a goddess. Oh, and a small percentage (if any) of pagan gods are NOT half immortal. Don't confuse gods with demi-gods.
But back on topic yeah, the bible doesn't support the 'God had sex with a mortal woman' arguement. That is pretty clearly explained.
