Threesome? in Starting Over

Yes my partner has gotten bored but we talked and it is not because of me. She just feels so unfulfilled at her job right now and needs something to build excitement. Our relationship has always been good but we think that is where we need the excitement. We have have talked about having a threesome but trying to figure out the dynamics of it is a little confusing. Just talking about it got us both more excited than we have been in the past year or so. Do we seek out another female and have a threesome of females or try to do the every males dream kind of thing. We are both bi-sexual or we have talked about both of us possibly being a-sexual. I must say that just talking about this has livened up our Friday night. I am so glad we talked and got to the bottom of what was going on.
