Teen's and sex

One day i was sorting through the internet like a normal day, when i came upon a article of STD's( sexually transmitted diseases) now most people know what  STD is and they know how to protect themselves. But even so the spread of STD's are on the rise, by 2030 50 % of women will have  STD and 40 % of Men that is a very high number. Why is this number so high? well speaking to my friends about it, condoms don't "feel" right, or it doesn't feel the same, i think that's a load of bull, your still getting sex, so what's the problem? either your going to get a disease, or your going to get pregnant, like allot of my friends. Looking around i see half of the people i went to high school with have a child, mostly the girls but a few of the men. Being of sound age now, it's not bad, but since some of the kids are now 3 i wondering if kids now days are getting taught about the dangers of STD's like AIDS, do they know the numbers  are actually on the rising, do they care? That is the sole purpose of condoms, so why are more kids using them? So what are kids now learning? I think there needs to be better sex ed classes, because the fact is kids are having sex as young as 14, and they need to be better educated so diseases don't spread. Now if your having unprotected sex or protected sex you need to get tested, condoms aren't 100 per cent. Now they are even making sites where you can tell the other person " oh no, i gave you a STD, sorry" via online message. Probably not the best way to tell someone.
