It really doesn't happen to everyone. There are outliers like us, OP. Do you want to date and have sex or do you only want it because society thinks you should? What do you personally want? Also curious, but how old are you?
You don't have to answer any of these questions if you aren't comfortable. I am just curious because I've also always been a bit of an outlier in society. Mine is in a bit of a different way than yours, but it's always interesting to hear about. I'm 30.
