Well, an environment is either sexist or it is not. It has little to do with the person experiencing it, in my opinion. They may react to it in a particular way, but that does not change the fact that an institution is sexist, etc.
As I stated, I receiving a pretty bracing education (and life) at school. I believe I am plenty tough.
I just don't think that, for instance, being groped by a male fellow in a supervision; or having fellows or male peers express surprise that I received a first - rather than simply congratulate me; or a whole host of other little events are simply evidence that I am or was not "tough" enough.
Personally, I think that on those, and other, occasions, perhaps the men should have been a little "nicer".
Did you experience such things, Bonsoir? If so, I'd be interested to know how you "[set] out to change them or else [worked] around them to [your] own advantage." In my situation, would you have slept with the fellow in order to avoid making supervisions frosty?
Should I have apologised to my teacher and my male peers for having done well when they, in the case of fellow students, did poorly? Did you?
