1) Can sex with someone you don't love be just as good as sex with someone you love?

No. It's better when the heart is there with the body. For me, anyway.

2) Is there a lust factor involved if so?

Lust always helps .

3) Can sex be better with a complete stranger than with someone you know?

Never say never, but I'd be surprised.

4) Would you have completely anonymous sex?

Errr...going back to "never say never". But I'm not out there looking for it.

5) Would it matter if it were same sex or different?

I don't think so.

6) Have you ever had sex with someone you do not know?

I've had sex with people I didn't know well...but never with someone I didn't know at all (online fun and games don't count in my book).

7) What is the shortest period of time you have known someone you have slept with?

12 hours. And we had a wonderfully cute and charming rationalization for how we were actually on our 3rd date by then.
