Inter-species Friendship-VERY common, with the occasional romantic relationship involved.  It’s rare with minotaurs and the other species, mostly because they tend to be very dogmatic about privacy and control issues that most of the other races don’t have too many issues with.

Almost always if the relationship turns romantic, the partners in the relationship adopt or use uterine replicators to have children of their own (with some genetic engineering to have the kids look like both of their parents, within reason).
