there's a bit of a difference between his gag as a ladies man/simp and his gag as a pervert
his gag as a pervert is really bad, him peeping on women in showers while using the raid suit to be invisible for example is just disgusting imo
but him simply barking for stussy, while goofy, isn't bad
Yep, this.
When Sanji is just being a simp, complimenting ladies and having heart eyes, and not being creepy about it, it's fine.
Being a perv against consent is never fine, and I am glad his own invisibility doesn't let him peep in the showers because basically Sanji is just moving very, very fast, and he cannot stealthily sit in the shower.
I am usually annoyed in cases like when Sanji is fighting Zeus to be Nami's slave (seriously?), him running away randomly in Wano and getting into a trap, something like that. The dog moment was meh, but not too damaging. The "only I can save Bonney-chan" was kinda icky. Nami body-swap was funny to me, but probably icky for others.
The whole "rehabilitation" period after okamas and FI nosebleeds were horrible to the point that I'm just trying to erase it from my memory.
