This is a pretty simple, short notion; yet, I don't think it really gets much real thought.
Women will ask me why am so good in bed. It always somewhat puzzles me. I'm not good or bad in bed, as far as I know. The last woman I slept with asked me, once again. "Why are you so good in bed?"
I thought about it and replied, "Because I only sleep with people I really like and want to make feel good and happy."
Think about it. Can you say the same? If not, you need to make some changes.
