What do I do? (Slight TMI)

So last night my boyfriend and I were having sex and everything is going really really well. I go to finish him off with some oral and he ended up finishing in my mouth. This is the first time that’s happened because he is really polite and tells me prior when he’s going to cum so no biggie. He feels like it’s rude to cum on me lol.

So anyways, he asked if the condom was still on and I tell him no after I spit that stuff out. He starts freaking out and apologizing like crazy. He was embarrassed and felt like an awful boyfriend even though I told him it was fine! I seriously didn’t mind and he was acting like he did the worst thing possible to me and felt guilty af.

I don’t know what to do or say to him that I haven’t already to make him feel more at ease. The most it was was just a surprise! I didn’t feel disgusted or wronged in any way like he’s making it out to be. I dunno ;_;
