My GF is a nurse anesthetist and tells me all the stuff about nurses. Lot of swingers, weird sexual stuff etc. Way more than the norm of other professions.
We think it may be they are under stress and need a "high" or something to counterbalance their day. Don't know though but there is definitely something to it.
Lol, not to scare you, but CRNA’s like your GF have the absolute worst reps, mostly because they’re provided beds in the hospital. I know one who’s threatened to write a tell all: “If Call Rooms Could Talk.”
