Avery Two people said the rapists were "winning" and I shouldn't be changing the way I live because of them.
I don't really understand that argument: what exactly would rapists gain from this, if they are 'winning'??
Yes, it would be ideal if you could prevent them from raping you, instead of needing to take action yourself, but as always if you have a problem, the only thing you can change is how you deal with it. You have taken a precaution that prevents it, and makes you feel safer, at no more than moderate discomfort for yourself I would judge (since you only wear it when needed).
