I actually have to count if want to know my number - I keep track of the people, not notches in my headboard
. Also, reducing it to a number is difficult for me because I don't believe sex is a clearly defined activity or set of activities.
I have shared my number with my partner and know his, we were fine with it since we know that we are both adverse to "slut-shaming" or "virgin-shaming", sex-positive people (the world at large isn't though, which is why I won't put an actual number here.) In this respect, the number itself isn't relevant, and shouldn't be to other people. Each and every of my relationships were important to me though, and have shaped who I am today.
