Safe sex is about a lot more than condoms.

Meet in a public place, like a coffee shop.
Set your own time limit for the meeting, arrange to meet your girlfriend at a particular place and time.

I can be anyone I want to be on the internet; I can be charming and persuasive on the telephone. But that does not mean you are safe to go off, alone, with me the very first time we meet. (You would be, but again, you have to take my word for that.)

You are embarking on a very intimate journey. Pack your lifeboat well .... because when you set sail on a voyage across uncharted waters, you can expect to lose sight of land.
