Don't forget to teach the high school kids to safely sanitize their whips and S&M/sex toys and to not share such instruments with multiple partners. Some of these sorts of courses actually do tell kids to be careful of the blood that is lost during some rough sex activities. Generally bleeding would indicate that something is already progressing beyond the bounds of "safe" activity but I guess these kids (and their "sex positive" instructors) are still learning.
More like "non-reproductive sexual misinformation" or "how unhealthy and risky behavior can be fun". This really makes me sick that our culture has degenerated to such an extreme. I am especially concerned for those who are young enough not to have ever known a more innocent time.
