Is it normal he said this at a wedding?

At a wedding reception for a lifetime friend, one of my other friends in the wedding party was sitting at our table. While his wife was away he told me she doesn't go down on him at all and is sexually frigid( this was the only girl he ever dated and ended up marrying). I didn't know what to say really and found it awkward sitting looking at them for the rest of the night. Maybe he figured I was drunk and wouldn't remember? Anyway is this a normal thing to say to someone you haven't seen in a few years?
