50% haven't brought condoms....not surprising surely? For a start only one condom is needed when two people are having sex and a lot of women expect the bloke to have one, they may have some themselves, but not always. So lets say men are mostly buying condoms...which is logical tbh, you've reduced the percentage, then you have the guys who either get them free, too shortsighted to bother, are having unprotected sex by choice and finally are having no sex. So out of all that 50% doesn't act like some shocking figure.
Same with not getting tested, if you're having protected sex at all times and have no symptoms, although it would be wise to be tested at some point, it's not surprising most don't. Then there's those who aren't promiscuous and so only have sex in longer term relationships where one assumes testing wouldn't be needed (again it might be best to, but doesn't happen) and again there's those who haven't had sex.
Then was sex ed in school lacking? Yes? Well no ****.
So....fail poll fails.
