Friend Sexually Negative

So I have a friend who is approaching their one year anniversary with their boyfriend but they’ve only had sex three times. She blew up on me and my roommate because she had told us she’d had sex and we were trying to be sex positive and encouraging since she comes from a religious family but got mad since she lied to her boyfriend that she didn’t tell us anything. Literally all she told us was that she took plan B and therefore we know for a fact she had sex. She didn’t say anything in detail and we didn’t ask anything other than saying she should have protected sex. We got communal condoms yesterday and then today we woke up to a text from her.

Like I’m not sure what we DID? She told us everything and my other roommate bought condoms that all three of us could use if needed. They’re latex free since the girl who bought them is allergic so they on it weren’t directed at the other girl. Should I be mad?
