Personally I think proper sex education (including sex orientation) should start in middle school (around 12-13 yr. old aka typical age of puberty) then continued the first year of high school and all students regardless of gender should be given condoms and birth control. Just because you give someone a condom doesn't mean they're going to go right out and use it, especially if they know the risks and consequences of having sex. There's zero reason not to do this, so many accidental pregnancies / abortions could be so easily prevented if people would stop pretending like sex isn't a thing.
