In 2011, a Florida judge sentenced a man to life in prison for raping at knifepoint a 22-year-old woman he met on a sugar-daddy site.
Emma, a 21-year-old University of Louisville student who is open with friends and family about dating sugar daddies (she says they tell her to live it up while she's young), has encountered her own scare.
One man who pays for her time is married, and although he wants dirty photos and Skype sessions, they've never gotten physical because he considers that cheating.
"But when I got there, he tried to push me to get physical, and he wouldn't take no for an answer. I was alone, vulnerable, and across the country from home.
It made me wonder what would have happened if I didn't get it under control," she says.
Recently out of a long-term relationship, Abby thought it might be something fun to try.
I'd never done anything like this or even been on a dating site, she says.
