On the topic of consciousness raising, all those sex ed classes did not prepare me for this when I was a teenager.  For being so eager to lose my (heterosexual) virginity, that when we got to his bedroom and he said he wasn’t going to be able to stay hard with a condom on, I just went along with it.  Of course, when I had sex with him 6 months later (and he knew I’d had other sexual partners in between) he had no problem using a condom.
