Odd Barters for Sex
Since the dawn of humanity, homo sapiens have used sex as a tool for getting what they want. However, back in the day, they bartered for survival, not for a couple extra bucks or the free shit like the following fine examples of modern humanity. Recent studies have shown that primates often barter sex for meat. Evolution has given us a very complex brain, but for these few unfortunate people, sex has been barter for a lot less. So much for the theory of evolution!
1. Woman barters for help with thick rain forest:
In recent news, the most popular barter-for-sex story has been from one Stephanie Gerson. As a college student studying abroad in Brazil, Stephanie wanted to explore the deep rain forest. Trouble was, Stephanie could not find a tour group willing to make this dream come true. 
But, this was not going to stop the very creative Stephanie, and she soon found a way to make her dream of exploring the rain forest a reality. Flirting with a college-aged Brazilian one day she soon found herself whisked away on a sex romp in the middle of the jungle. The price? To be able to sleep in the middle of the jungle, live in temporary palm huts they made, and eat piranhas and such. To me, this sounds more of “I wanted to have sex with the locals” instead of what she says was a pure business deal. “The rumble in the jungle” never had truer meaning for this girl than that unforgettable weekend getting down and dirty. - Source
2. Sex for Gas:
Everyone knows gas can be expensive. Everyone knows the economy is down. What does Kelli Still do about this predicament? Well she decides to barter some gas money for sex— in this case, oral sex. Kelli Still offered some head to a man. 
The man somehow obliged (look at that mug). Anyway, this is where the story gets a little crazy. Apparently Ms. Kelli Still decided to get angry and took scissors from the man’s house. One thing led to another and the man was stabbed several times and right below his right eye and the back of his head( his actual head, thank god). Kelli Still got the worst of it getting arrested for assault and a partially severed finger for her troubles. Now i don’t blame someone trying to get free gas and I would do just about anything for some, but seriously you are just causing more trouble for yourself when you start getting stabby after wards. Just keep it to “wam bam thank you mam” is my motto.- Source
3. Sex for Potato Chips?
Lohoma Sue Smith isn’t your typical prostitute. Sure she goes to trucker stops like most others, but Lohoma has a problem other than the obvious. She loves potato chips, and when she is hungry, Lohoma gets what she wants. 
While doing her thing at the truck stop one evening, she spotted the holy grail - The Frito-Lay man. Holy shit. So Lohama bartered for one of those $30 dollar packs of Frito-Lays. You know the ones that you buy thinking they will last you a few weeks then you are covered with a few dozen empty packs laying all around you later that night. Yeah, those. Anyways as Lohoma would soon find out she is not all that and a bag of chips and was arrested for prostitution for her third time. - source
4. Sex for gas(Again!) - Crude Oil
The United States sells out contracting rights to oil areas around the globe. Who gets these rights? Well in this case it turns out, the contracts go to whomever hosts the best sex parties. 
White-collared US agency workers turned this into their own private sex orgy job. Where as gifts for rights they would be able to hook up with some of the companies “employees”. Yeah i am sure it wasn’t the CEO pimping themselves out, but some fine skilled workers in which business they know nothing about. These guys were busted, but who knows what actually happened to them. The scene was described as a frat part climate, hell I have been to frat parties before and I do not believe I have seen anything like this. But hey i do not remember everything that has happened at those parties.- Source
5. Marcia Brady : Sex for Cocaine
Not that this is necessarily odd, but its odd that Marcia Brady(Maureen McCormick) is the one behind this nonsense. She would sell herself for cocaine during her famous time. Wait, didn’t she have money though? Yeah but she still did this stuff. She was seeing at Sammy Davis Jr.’s place and the Playboy mansion doing god knows what. I can tell you one thing, she was not paying attention to the life lessons that the Brady bunch was putting out there. I just wonder if she ever did blow with Oliver the unsuccessful cousin that came along in the last season. However, after hearing this it would not surprise me.- Source
As stated earlier, this has been going on from the beginning time. There will be many more to follow and only they can set the bar lower than these four. Hopefully, there is someone out there to conquer all that have gone before them and truly make the oddest barter the world has ever seen.
