Bringing a partner into the relationship

Hey girls.

Have any of you ever brought someone into the relationship?

Since I had my son, I’m not in a very ‘let’s have sex’ mindset. Ever. I would be totally ok with maybe having sex once every few months.

I do understand that he has needs though, and the more I think about it the more I think I’d be ok with bringing someone else in for him. I haven’t brought it up to him at all, and honestly I doubt he’d even entertain the idea.

I’m really just looking for experiences, good or bad, to help form my opinion of whether I want to suggest this.
