I- Is Nagatoro actually not a virgin?

Disclaimer: I've been watching the anime and not the manga, so I might not have all the information.

ANOTHER disclaimer: Idk if this is allowed here so lmk if it's not.

I Nagatoro is always bullying Senpai about being a virgin, but I'm wondering if she really isn't one. I can easily imagine her friends doing the deed with someone random, but I feel like Nagatoro isn't the type of person to do it with someone who isn't in a close relationship with her. What do you guys think?
