Hayward is married...with children, but if he wanted to cheat on his wife, it isn't exclusive to Miami and it isn't exclusive to just bikini-clad women. There are plenty of women (hot and willing to cheat) everywhere.
Look at the link below, from 2015, which ranked the cities with the most cheaters using data from the Ashley Madison hack. It includes all cities in the world, but I'll only include ones with NBA teams:
http://www.independent.co.uk/life-style/gadgets-and-tech/news/ashley-madison-hack-chart-shows-cities-with-most-cheaters-10463389.html2. New York City
4. Toronto
7. Houston
8. Los Angeles
10. Chicago
15. Brooklyn
16. Miami
18. San Antonio
19. Dallas
24. Atlanta
15. Philadelphia
On this list, Miami is 7th according to cities with NBA teams. I acknowledge that the larger cities are on top, because they have more people (hence, more cheaters), but Cheaters will cheat anywhere they go.
I acknowledge and thank the lək̓ʷəŋən peoples of the Songhees, Esquimalt and W̱SÁNEĆ First Nations for allowing me to live, work and play on their unceded traditional territories.
