Everything MickeyLee has said in this thread. I agree with all of it. I've not given the talk to a daughter, but I gave a talk to a female cousin. She's actually older than I am, but completely inexperienced. She wanted to ask things she wouldn't have asked in Sex Ed, her mother, etc. I focus on safe sex practices, consent, communication, and being open minded. Condoms, dental dams, lube, and getting yourself screened regularly, especially if you're being intimate with multiple people. Be extremely clear on what you consent to and don't fool around with someone at the very least for the first time when either of you is under any kind of influence. I've lost out on getting laid, because I wanted completely clear headed judgement calls from everyone involved. Oh well, there's other times or if there aren't, it's a good thing you waited. Just because one person's kink isn't your kink doesn't mean it's bad. Sex isn't something to be ashamed of. Choosing to be other than monogamous is perfectly okay, so long as anyone you're involved with knows what's up. Monogamy isn't for everyone. Poly isn't for everyone either, though. Jealousy and feelings happen, it's how you handle them that's really important.
Edited to add: I rambled, but given I mention dental dams, yes, I at least briefly discuss oral sex.
