comparing sexual partners

I know it’s not fair for me to compare two very different people, so how do I stop comparing my new girlfriend to my Ex? Help!

I have slept with seven men: five bona fide boyfriends, one guy I was seeing for a time, and one one-night stand. According to Slate’s sex history calculator, which is based on data in the General Social Survey from 2006-2014, I have slept with more people than 53% of my female peers, which I think gives me an edge comparing the sexual performances of men.
