Soulful
Another angle might be that, since Wands are associated with passion and passionate sexuality, maybe he feels guarded because he doesn't want to let a physical attraction draw him into a situation he might regret later. For instance, a man who is extremely physically attracted to a woman but who doesn't believe in getting physically involved if there's not a serious possibility of a relationship, but who either isn't ready for a relationship because he has other goals at this time or else he thinks the woman might not be a good match for him for one reason or another and he doesn't want to go through that.
What would your thoughts be on pulling the Ace of Cups as a clarifier for Nine of Wands as feelings? Is he afraid of over flow of romantic feelings?? Or a new beginning with someone? I really resonate with your interpretation of Nine of Wands itself as feelings , very on point! Thank you
