Update: Husband introduced me to someone

I posted about my husband approaching me about wanting me to be with other men. After getting a lot of good advice from people on here he and I have had much deeper and better conversations about the idea and I’ve come to understand better why he wants this and also believe that he is being very sincere and genuine about it

Since those conversations he has introduced me to a guy from his gym, he is an older gentleman, and we have only been texting so far. He seems like an incredibly kind, smart and sweet guy but I feel so nervous chatting with him. Not in a bad way but in that way you would feel when meeting someone new you are interested in.

I suppose these are normal feelings? Even more so considering the circumstances?
