Snooki lost her virginity to a "jerk" when she was 14.
The former 'Jersey Shore' star, who has an eight-month-old son Lorenzo with her fiance Jionni LaValle, has confessed that her first sexual experience was "terrible".
The 25-year-old reality TV star told YourTango.com: "I was 14. I mean, in upstate New York there's really nothing to do up there but experiment.
"He was a senior, and I thought he liked me but turned out he was just a jerk. So, it was terrible."
The pint-sized beauty says that her fiance has restored her faith in men and she knew within three months of dating him that they were meant to be together.
She said: "I just realised that he was everything I've always wanted, and I could talk to him about anything. Once you realise the guy you're in love with can be your best friend and lover, I mean, it's meant to be."
The couple haven't started planning their wedding but hope to tie the knot in New Jersey sometime next year.
She said: "I have no idea about anything yet. We realised we want to get married sometime next year. No date set yet, and it will probably be in Jersey. I would love to write my own vows. I just have to convince Jionni, 'cause I don't think he wants to."
Snooki is surprised that she has completely changed since the birth of her son.
She said: "How much it has matured me and made me grow up. I'm a totally different person, and I absolutely love it. I didn't expect motherhood to be like this! I talked to a lot of mothers before I gave birth, and they said get ready to be stressed out of your mind with no sleep. Even though I get no sleep, I'm not stressed yet. I'm in love."
