Three some with husband

My husband recently brought up that fact that he thinks I may be into girls and honestly I have no idea never been with one 🤷‍♀️ any how he was telling me how I could be getting fucked by him while a girl played with my boobs in such. I said okay. Never had a threesome and don’t know much about sex really. He said no cause I’d get jealous he thinks and he knows I wouldn’t like seeing him fuck a girl.

Couple questions:

How do we even find someone?

Is he wanting one secretly?

Did I mention he brought this up in the middle of fucking me and has been drinking??
