Be glad and thankful that you can have that convo with your son. I don't know about you but my "talk" about this subject from my parents was "don't get a girl pregnant." Rhetorically speaking, sex and having sex are part of the human condition, so why are we scared to talk about it?

I have these convos with my daughter and son frequently and it makes all the difference in their growth as a happy and healthy adult. Although they're pretty annoying and cranky teenagers right now.
