Who did Serena lose her virginity too?

It was definitely not Nate in the Показать like it was in the books, as we know that in the Показать she had sex with Nate during Sophomore Year, but she made the quote in 1x12 to Dan;
"In Freshman год I dated the swim team captain, and he gave me a key to the pool so we could go and.... Ты know..." (clearly hinting sex)
So we know by the time she had Остаться в живых her virginity during/possibly before Freshman Year.

We just... don't know who to...

Damn, now I want to know! Hahah!

Ya I think Serena was suppose to have Остаться в живых it to Nate in the pilot but when it came down to it the Показать became way different then the books. For sure Nate Остаться в живых his v-card to Serena @ the Shepard wedding (Chuck сказал(-а) it), Blair Остаться в живых hers to Chuck jr год (limo ride any1), and Chuck Остаться в живых his to Whoregina in 6th grade (Blair сказал(-а) it). That's all I know sry.

in the Книги she loses it to nate but in the Показать ,don't think so .it might have been carter baizen ,just guessing here ,i have no proof .

In the Книги it was nate but in the Показать I HIGHHHLY doubt it, its some Болталка that we don't know.

It's never really revealed who Serena loses her virginity to.
