Option A and B are both erotic adventures , its like when woman/men go from one sexual partner to next , the level increase just like in a video game each level has a new more powerful boss, in Option A woman will go from one sexual partner to another but depravity, kink , will increase with each level,  on Option B male guy will hunt a new woman or girl and difficulty level of seducing(pataana) will increase i
With each new woman/ girl

Still B feels very regular. You can increase the difficulty in seducing with every new girl, but feels caricaturish. It becomes get a girl, use her, move to next. While with a female protagonist we can play much better there are n number of possibilities, like you stated in your question. And sex stories need a kink it to it, where B fails in comparison with A. Overall it's upto you, what to write, and not abandon the story. All the best for the story.
