Nonexistent, except for a comment from my mom once that she didn't understand why drugs were illegal, didn't care what people did in their own homes.

With my kids just an open door communication style, they ask I answer - so like when one got a boyfriend and both were first timers, she asked about STI, was it safe if she had birth control, and we talked about the HPV, HIV, Hepatitis, things you could possibly get from being born or nonsexual contact, but also about relative risk, and how there is always going to be some, but that shouldn't stop you from living, being open and talking with your sex partners. And talked about enthusiasm rather than consent, that you should not push anyone for consent, wait until both of you feel enthusiastic about sex to do it.
