I had a hard time telling my husband about my encounters with another woman. I think I was afraid if I made it sound too good, he'd feel inadequate, but it's also hard for me to put what happened into words. I did well recounting all of the details when he asked me specific questions ("did you play with her breasts? what was that like?") or put it in a chronological context ("what did you do first? then what?" etc.) though. So asking detailed questions and telling the story from the beginning might be helpful?
