I've got a friend who does it through that sugar daddy website. Usually she has a few sugar daddies that she sees once or twice per week. She earns a bunch of money. She seems to be happy with it, though if the guys are creepy or the sex is really bad/weird she finds new ones. Seems to be really easy to find guys willing to pay hundreds of dollars to hang out or to fuck, which is shocking to me. If I had a bunch of money I wouldn't pay hourly for sex, but what do I know? I don't judge her, I encourage her because I get good stories most of the time and she seems happy enough with it. She does it to pay for school and just to have spending money. She doesn't really save, maybe she thinks it'll last forever. She won't be a hot 20 year old forever though so hope she figures out what's next at some point.
I wish women would pay me, I give it up for free too often. Almost had a sugar momma once. Long story though and not worth telling. Also, kind of had a sugar momma, though she didn't give me money for it, she just took me to nice restaurants and drove me around in her nice car, that sort of thing. I never once paid for anything, including hotels, wine, etc.
