1) Can sex with someone you don't love be just as good as sex with someone you love?
Physically, I suppose. But that is too simplistic of an answer. You have to take into account the spiritual aspect of being intimate with someone you love. I am a romantic at heart, so I would have to answer no, it would never really be as good.

2) Is there a lust factor involved if so?
Quess so.

3) Can sex be better with a complete stranger than with someone you know?
Not to retract what I said in #1, but yes. All other things being equal, the risque factor and taboo of it all would be exciting.

4) Would you have completely anonymous sex?
No.

5) Would it matter if it were same sex or different?
I'm straight, so no.

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

7) What is the shortest period of time you have known someone you have slept with?
Less than an hour. *Blushes*
