I (f22) hid my period from my boyfriend (m23) because I was embarrassed. How do I tell him the truth?

I was trying to make it a special night with my boyfriend. We had sex for the first time in a while. It’d been almost two weeks since we’d been intimate, and I was on my period. It was just in the beginning stages and I was only bleeding slightly, but I really didn’t want to tell him because I was embarrassed. I just hid it, and it was a bit uncomfortable because I had a tampon in and it was sore.<br><br>He was a bit confused, but I just said that I was tight because I hadn’t had sex in a while. He believed me, but I started bleeding more when it was over. He was upset, asking if he had hurt me, but I just said that I had stress-related vaginal bleeding, which I do get. I hid in the bathroom for a while after because I didn’t want to face him.<br><br>I’ve told my boyfriend everything up until this point. He was my first boyfriend and he was my first for everything. I’ve been too embarrassed to even leave the bed the past few days because I feel so ashamed. I do know that periods are natural, but I just don’t know how to feel okay about it.<br><br>How can I get over this and tell him the truth? I don’t know if I can tell him because I don’t want to see the disgust on his face.<br><br>TLDR: I was on my period and hid it from my boyfriend because I didn’t want him to see the blood. I feel ashamed and feel like I’m hiding a secret and it’s starting to weigh on me. How can I tell him the truth and not feel so ashamed?
