不安感 fuankan. Feeling of uneasiness, anxiety, discomfort. If you've watch anime, you've heard this before "fuan"
變恣度 is not a japanese word/expression (if it is, not even Jisho knows it). But all three are used as kanji. First one 變, means change. Second 恣 means selfish or arbitrary. Third 度 means -do used as unit measurement º as in degrees (i.e. temperature or angle). Sooooo like, degree/level of arbitrary self change, which makes sense as a sexual corruption degree, similar to what killerjeb said "lewd level".
