If you'd known someone since you were 12 & 14, and were now 35 & 37, always had a lot of affection for each other but in a platonic way and had recently started spending more time in person together recently, where you've notice a little change and some tension/light flirting, would you "go there" romantically/sexually?
Have you ever? Did it work out and you lived happily ever after or did it mess everything up?
