My Wifes Turn On

My names Bruce and I have a wife thats a nurse. I need a womans opinion on something. When my wife gets off work, she usually tells me about her day and everyday is usually pretty similar. However, lately she has been coming home talking about how a few of her older patients will check her out and make sexual comments. When she told me this, I asked her to be more specific. She told me that one of her "hung" patients has "winked at her, grabbed her ass and said things like "can you take care of this boner" then showing her his massive cock. What really concerns me is that she seems to want to fuck right after telling me all this and is always really horny. Should I be concerned??
