Re: advise

This is completely new to me as well. I am in my second marriage and we have been “happily” married for just over 20 yrs, but in the last few years I have been unable to satisfy her sexually. At one point she brought up the idea of having a sexual relationship outside the marriage, but I didn’t think she was serious and let it go, but recently, it started me to think about this whole subject and it turns me on to think of her having sex with another man. I just don’t know where to go from here. How do I revisit the idea that she brought up without making myself look like a complete fool?
