I have to vote NO. Each one was different. My present girlfriend would be great considering we had sex a litle more often! I think the main thing or focus is to communicate and respect the other person. Love and sex are two great things.
I am currently single. I am a very hard person to make cum, I have one ex in particular that has not only made me cum but left me shaking afterwards. We have been friends for years before we started dateing and even today we are still friends although we are not together. He makes me want to jump his bones every time I see him.
