Too Many Sexual Partners

I lost my virginity in 2016 and since then I have slept with 11 people. I have only loved 2 of thse people. I know it's not horrible to have slept with multiple people but I can't help but feel so empty and guilty. The man I'm with now have no idea how much it haunts me. I regret it so much because I wish I had limited myself. Is this bad? Should I really feel so guilty? How do I stop feeling so much pain when I remember?
