Who did Serena lose her virginity too?

It was definitely not Nate in the दिखाना like it was in the books, as we know that in the दिखाना she had sex with Nate during Sophomore Year, but she made the quote in 1x12 to Dan;
"In Freshman साल I dated the swim team captain, and he gave me a key to the pool so we could go and.... आप know..." (clearly hinting sex)
So we know द्वारा the time she had लॉस्ट 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 लॉस्ट it to Nate in the pilot but when it came down to it the दिखाना became way different then the books. For sure Nate लॉस्ट his v-card to Serena @ the Shepard wedding (Chuck कहा it), Blair लॉस्ट hers to Chuck jr साल (limo ride any1), and Chuck लॉस्ट his to Whoregina in 6th grade (Blair कहा it). That's all I know sry.

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

In the पुस्तकें it was nate but in the दिखाना I HIGHHHLY doubt it, its some बिना सोचे समझे that we don't know.

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