Hi there, welcome
Not sure what they mean by “hormonal”? How long ago was he neutered? Sometimes in first dates mounting and other territorial/dominance displays will happen, and these often are similar to a hormonal bun.
Has the rescue been trying to bond him for you, or just doing speed dates with possible matches?
It’s pretty rare for buns to fall in love at first sight. In my mind, the speed dates are good to figure out which buns are definitely NOT a good match (outright and immediate aggression is no good), but you might not find one that is just perfect right away. Also totally fine to wait until a bun comes along that is a good match and that you like.
Some buns are better as singles, but I’m interested to know more about his behavior towards other buns.
You might also suggest trying him with another male. Sometimes boys that grew up with their brothers get along well with other males, so it’s worth trying!
