F 25 Accidentally showed one of my close friends my bfs dick

This happened last week at a get together , we were showing each other pictures we had taken the last couple months and i was flippin through pictures on my phone and forgot i had my bfs nude were on there and i gave her my phone and as i kept telling her to swipe she gets to the picture and says “omg who is that its big” and i got nervous and said “um thats my bf im so sorry” and she got red and gave me my phone . It was so awkward afterwards and i told her im sorry once again and she playfully said “no its okay its pretty” i felt so bad but also funny how we both got so stunned once we got to the picture. My bf doesnt know about it should i let him know ?
