I agree it wouldn’t stop those who will do it regardless.
it will deter a handful if we’re very lucky but most importantly is it will stop those who’ve attempt rape from doing it again as well as halting self pleasure given the damage.
As for wearing; it may be a bit uncomfortable the first few instances if you are not used to using things like a tampon or me steal cup, we get used to those very quickly.
For some it would be unnoticeable, not to the point that you forget it’s inside you but that you don’t notice it’s in there.
For some it would be very noticeable but not enough to cause any distraction.
Given the material it’s made from and the lightness of it it would definitely be easier to adjust to than typical contraceptive devices
