The 23-year-old singer was left devastated by failed relationships with older stars including Jake Gyllenhaal and John Mayer and now prefers to date younger men such as Conor Kennedy and her latest love Harry Styles, both 18.
A source said: "Jake and John made her feel inferior. With younger men, she really feels like she's in control."
However, even if her latest relationship doesn't work out, unlucky-in-love Taylor is happy she will have material for a new album.
The insider added to In Touch Weekly magazine: "Taylor's a serial dater. She gets too clingy with guys or she gets sick of them. Harry will break her heart but isn't that the point? It'll become material for her next album."
The 'We Are Never Ever Getting Back Together' singer recently admitted she is "obsessed" with love and even bad experiences don't put her off her quest to find The One.
She said: "I think about love all the time. I have done since I was able to comprehend what love was, I daydream about it all the time.
"There was a relationship that was an extreme let-down, one that was a betrayal, one where I got cheated on, one where I had my self confidence chipped away piece by piece ... But even after your heart explodes into a million pieces and you're thinking, 'Why did this have to happen?' You make eye contact with someone across the room and it clicks - and bang, you're in love again."
