Boy problems please help

Anika • I'm 15 :-)
I'm only 15 and I know I've had a lot of boyfriends for my age. But I was always around the wrong people and I felt as if I needed one. I have better friends now but I'm realizing that everytime I've had a boyfriend they've been rather creepy or stalkerish. I don't want this to keep happening when I'm older. Any tips? I'm actually kind of scared 😓
