Take the real number and divide by two. Of course, if you happen to be on an odd number that means you have to explain having slept with half a woman. Just say that they looked like a woman, but they'd only had half the op.

If they ask what you're thinking before you answer the question, the only correct answer is 'still counting'.

I think when a woman asks 'What are you thinking?' it shows insecurity.

Personally if i were asked that after a passionate session the answer would probably be 'I could murder a bacon sarnie!'
