I was at school in the late 90s. I see things online now about "body count" and how that can be used by some to shame people (women). I don't know about your school and the general attitude around at the time, but it really seemed like the opposite was true back then. The cool people at school were the ones who had experience. Admittedly my town did have the highest teenage pregnancy rate in Europe at the time. Was this the case when others were at school? People didn't seem ashamed of sex when I was at school. It was the opposite, they were very proud of it and laughed at the inexperienced people.
