Ain't sponsorship just sugar-daddies with a different name? This has existed since ever, I only say while I would not choose that lifestyle one should be careful not to come out empty. I would not choose it because life has afforded me some advantages like the fact I can innovate and create ideas that allow me to be an independent woman.
Thus like @jeanwandimi I would not judge till one plays their cards wrong and the guy leaves you high and dry.
