I spent a summer going to swing dance lessons with a woman 20 yrs my senior. There was no sex involved. Quite honestly it was the best time I've had since being in my last serious romance. You can enroll in a class, even if you don't have a partner-and often there are others looking to pair up as well. At the end of the night, there is no pressure to go home with anyone and you often get to dance with different partners so it's getting great exercise while also being able to nonchalantly "check out" the other team. Double dip if you like or keep it clean if there's no attraction, no harm done. Dancing is the world's best natural medicine for the soul, hands down-and the most fun you can have with your clothes on.
