is it bad

I lost my virginity to a random I met on vacation when I was 15, after I felt awful, so sad and guilty and swore I wouldn't have sex again until I was inlove, a couple months later I did it again with another random, it lasted a solid two seconds no joke,( I was sad afterwards btw) the next time I had sex was with someone I genuinely cared about but obviously didn't love, we hooked up a few times. ( didn't experience sadness). The other day I hooked up with a random and I have the feeling of guilt and sadness all over again, I feel so dirty for not being a virgin at 17 and I don't know how to get over it  help
