I have a, unfortunately, hypothetical question.

Things will usually move at their own pace, and topics like sex will come up when they do. Sometimes you can influence when to have those sorts of discussions, but in my eyes stuff like that comes up by other means.

I don't want to get too deep into my own personal experiences with it, but generally speaking it happens when it happens. Go with the flow and try not to set out an agenda for stuff like that. It'll be much more fun when it happens!

Or, the short answer, whenever you're ready.

 

Yes, what King has said is right. Nothing more needs to be added ; )
