We have far too little to go on with Taylor and I understand its all just speculative,but with that Harem Queen Perk, I cant help but think if you're not romancing her Solo and have other girls on the go, SHes gonna pounce at it and a harem is the only way to go.That may be an choice further down the road, but so far we have far to less content with Taylor, to be sure of much.
I don't think that bj competition will be a major point thought.
I can imagine if you show interest in her, as well as Katie and Violet, which are both her friends, that could open the path for her to be harem queen or solo.
I could be looking at it wrong and without her a harem is just harder to get. Not impossible by any means, just harder.
