my question as always. what happens when one partner won’t offer any sort of sex for years upon years? Divorce? Even the Catholic church allows annulments under such conditions.
That is not correct. If a marriage was never consummated, then it is not a sacramental marriage, and can be recognized as "null." This is true, btw, if the "kind of sex" was contraceptive - because this is contra bonum prolis, and therefore the assocation was not a sacramental marriage. If either party never intended the association to be permanent or exclusive, then it is not a sacramental marriage.
If medical or psychological problems arise, resulting in sexual dysfunction, then medical or psychological help is in order. However, if the problems cannot be resolved - just as with any other medical or relationship problems - this is where you take "in sickness and in health, for better or for worse" seriously, or you're an oathbreaker.
