My parents never gave me 'the talk' nor did they ever speak about anything remotely sexual around me.
I learnt what I know - and I think I know quite a lot - from school sex ed, the internet (which at time can be THE WORST place to learn stuff) and other people.
I hope that sex education improves from what it was when I was younger - though my school was fairly thorough; my partner was taught very little if anything. He's literally learnt stuff from me, even the scientific stuff, in the last year. We're in our 20's...
I'll be open about sex with my children. My mum was, and still is, extremely prudish around the subject and I think it's pretty stupid considering how (almost) EVERYONE does it! I probably know more than my Mum now too because I'm open to learning about it and will share it with my children when the time arises.
KNOWLEDGE IS POWER CHILDREN! NOW GO FORTH AND SAFELY F*CK!
