meaningless sex

I'm 17 years old and I have never had meaningful sex. I have been with 8 different people and I feel like such a slut. I don't know how to get over it. I'm so upset even though it was my decision to sleep with a person that I didn't love. At the beginging of this school year my body count was 2 and now it is 8. How to stop being so sad that my body count is 8 and I never loved any of my bodies?????
