Reason: cum_exchange has been around for a while, and while I do find the concept useful to tag, the name has never sit right with me. About 2 years ago (see topic #27963), I made a very confused attempt at formalizing the broader concept (alongside the even more vague "transfer" group, to make things worse) and added a handful of companion tags. This BUR renames them all to use "transfusion" instead.
The idea is that "blood transfusion" is a term that's broadly understood, with a definition along the lines of "you put more blood in someone's blood tubes and now they have more blood". Reusing "transfusion" for what's currently being labeled as *_exchange is meant to convey something more like "you put more blood cum in someone's blood cum tubes and now they have more blood cum".
Alongside this change comes a slight, but significant adjustment to the definitions, making them looser, hopefully for the better. The current definition for cum_exchange reads as follows:
Cumming into someone else's penis and inside their balls, either directly through urethral_penetration (usually penis_in_penis) or through intermediate tubing (possibly a urethral_tube) connecting both penises.
That description puts a restriction where there clearly needs to be two participants, the cum in question is not supposed to come from a "cold source" like some sort of "cum bag" or "cum tank". To avoid confusion, the new description would lift this requirement. The same applies to the other exchange tags. I will be adding a note in the new description that these are "usually done through same-orifice_transfer (urethral_transfer, anal_transfer, nipple_transfer, etc.)" as well, to highlight how that may not always be the case.
I am aware that feces_transfusion and egg_transfusion are both improper, since "transfusion" is only said of a fluid, which is why the real life procedure for the former is called "stool transplant", for instance. This is intentionnal, so I can group them all under the same paret tag without having the name vary across the tag group, but I would be willing to change that if good points are brought up in that regard.
