I am 32-years-old and still paying on college debt. Had I been given the opportunity to "hang out" with an older lady in return for tuition or books while I was in college, I would have signed up in a heartbeat.

According to Wikipedia, a Sugar Baby is "a person who is in a specific type of transactional sex relationship for the expressed purpose of achieving economic security. A person in such a romantic relationship may receive cash, gifts or other financial and material benefits in exchange for being in the relationship."
There is a website to be/get a sugar baby called SeekingArrangement.com, and they just said that Colorado State University is one of the fastest growing sugar baby schools of 2019.
