That's a bit different, the issues with trauma from sexual abuse can lead to sexual promiscuity but it doesn't follow that having multiple sexual partners means you are suffering trauma from sexual abuse. And neither imply what an individual would be comfortable doing in a sexual relationship.

If you are a better athlete than me, you are doping. Or some such logic. Some people have more sex than others, both are good.

Yup! In particular judging someone on a single axis and using that to come to conclusions about what sex acts they'll do or won't do with you is a very jaundiced, objectifying way to look at another human.
