Wow. Thats a question that should never be asked unless your willing to hear the answer.
The way i look at sex with a new girlfriend is this. When we have sex with each other for the first time. It is our first time. It is as if we are both virgins for each other. After all, everybody like things a little different then others. So you have to explore your partners desires. Be open to new adventures with sex.
You really can't think about the past. You will drive yourself nuts.
