Infatuate rom question

So, I had a caster sim with no romantic preference cast the infatuate spell on a male sim to a female sim. Then, the male sim walked up to MY sim and started making out with him. I had planned my sim to marry his childhood friend (girl), and start a relationship with them as young adults, but now he has a boyfriend. 🤣 I hadn't expected him to be gay, but thems the dice. Anyone else have this happen?
