The ones that got away. Missed sex opportunities that you wish you had acted on?

When I was in the closet and even after, there were several guys I realized afterwards I could have and should have hooked up with. There was a really hot twunky waiter who was so flirty and even pressed his dick against my shoulder when pouring water, an Uber driver that kept making eye contact and then I noticed was sporting a large bulge when I went to got out, a landscaper at a hotel that found reasons to chat to me with his hands occasionally going down the front of his shorts... so many times and so many regrets. Do you have times you wished you had followed up on something only in hindsight?
