Ketubot 11B

ואין להן טענת בתולים.

and they are not subject to a claim concerning their virginity. Since they were married, even if they did not have sex with their husband, their presumptive status is that of non-virgins, and the second husband cannot claim that he was misled with regard to their status as virgins.

הגיורת והשבויה והשפחה שנפדו ושנתגיירו ושנשתחררו, יתירות על בנות שלש שנים ויום אחד ⁠— כתובתן מנה, ואין להן טענת בתולין.

And similarly, with regard to a female convert, or a captive woman, or a female slave, who were ransomed with regard to the captive, or who converted with regard to the convert, or who were freed with regard to the female slave, when she was more than 3 years and one day old, for all of these, their marriage contract is 100 dinars and they are not subject to a claim concerning their virginity. When they married, their presumptive status was that of a non-virgin.

גמ׳ אמר רב יהודה אמר רב: קטן הבא על הגדולה ⁠— עשאה מוכת עץ. כי אמריתה קמיה דשמואל, אמר: אין מוכת עץ בבשר.

Talmud: Rav Yehuda said that Rav said: A minor boy who had sex with an adult woman renders her as one whose hymen was ruptured by wood, as the act is not considered full-fledged sex. Rav Yehuda continues: When I said this statement before Shmuel, he said to me: A woman does not achieve the status of one whose hymen was ruptured by wood by means of flesh, i.e., sex.

איכא דמתני לה להא שמעתא באפי נפשה: קטן הבא על הגדולה, רב אמר: עשאה מוכת עץ, ושמואל אמר: אין מוכת עץ בבשר.

Some teach this halakha independent of Rav Yehuda: With regard to a minor boy who had sex with an adult woman, Rav said: He renders her as one whose hymen was ruptured by wood. And Shmuel said: A woman does not achieve the status of one whose hymen was ruptured by wood by means of flesh.
