My advice is “earlier than you think you should” and “more often than you think you ought.” Thankfully there are better informed people than me.
Eryn-Faye Frans is a sex educator and a long-standing friend (I have known her since she was born!). Formerly from Vancouver, Texas, Scotland, back to Texas and then Vancouver and now in Toronto — its been hard to keep up with her — Eryn-Faye is a great parent, a loyal church-type (though not at all “religious” in the stuffy meaning of that) and provides thoughtful and thorough advice and hope to couples who are finding their sex life less than lovely. (I actually don’t know how a sex educator could possibly be stuffy.)
* Spread out the conversations
* Use anatomically correct terms
* Don’t lie
* Don’t assume
* Don’t judge
* Pass it on
I found this advice helpful. I hope you do as well. And sign up for Eryn-Faye’s blog — you will learn lots of interesting stuff.
