Watching your ex with someone else can be like rubbing salt into the wound. On the other hand, it may be the final push you need to let him go.
Some people have sex, fall in love, and live happily ever after.
Others feel embarrassed and horrified the next day. Before sleeping with a virtual stranger, you have to consider safety and disease - then decide whether the romp is worth the risk. For some, not having a past with a man can lead to a night of anonymous athletic bliss. But others who get too intimate too soon are left feeling vulnerable and regretful. So know what you're getting into and make sure you're in control, not just following his lead.
