You've had a great 4th date with a handsome guy. As far as you know, he is only dating you and not being intimate with anyone else. For this date, you decided to have dinner at his house. This man/woman lives alone and you're 100% sure he doesn't have any room mates. In the middle of the date, you excuse yourself to use the bathroom. While using the bathroom you notice a used condom in the garbage pail and it's evidently fresh. Dinner has not yet been served. What do you do?
ETA: He has claimed since meeting, that he has been celibate 7 years and is not sexually active.
