I heard that an easy way to make some quick cash is to donate plasma and/or semen. Apparently people pay money for that kinda stuff nowadays. 
So my question is… where’s a good place to find resources for these kinds of things? Like, a list of places that will pay for my fluids. I regularly donate blood, but I don’t know if the Red Cross is the place to go or not?
Thanks for your help 
From my medical experience as an inner-city doc, not as a source of fluid:
Most inner cities have plasma centers. Ask the local street people, it provides some of them with most of their income. Don’t expect cookies and juice when you’re done. Google “plasma center” for a clue as to where to find them.
To donate semen you generally have to pass a rigourous screening procedure with an accredited fertility/insemination clinic. If accepted, be prepared to abstain from orgasm for up to 4 days at a time when you’re “on call” if they’re looking for you to provide fresh semen. Here’s an IVF site that accepts donations from qualified men. An advanced degree is preferred: http://givfcryobanks.com/
