Me (23f) and my boyfriend (26m) had our first argument right after we had period sex and I need help approaching the situation.

We’ve been official for almost two months and we’ve known each other for about a year.

Last night we had sex while I was on my period. Which was completely unexpected as I have said to him previously I hate period sex. I have explain the reason, the past I had birth control complications which made me bleed everyday, so bloody sex with my ex made me feel disgusting. With my boyfriend he reassured me he didn’t mind, he was man enough and he made me feel at easy, so when we were in bed late at night, I was in the mood, I initiated and we did it. It was incredible bla-bla. Then 10 minutes later he says he has to go home as he’s got a busy morning the next day. That wasn’t unexpected, I knew about it.

The problem is, as a joke, I said : next time we should do it earlier so you won’t leave so soon. I meant it as a joke or just you know a little comment, like yeah I meant but I wasn’t mad or blaming him. He immediately got super defensive, saying he’s not that kind of guy who leaves straight after sex, he’s not an asshole, he did not expect us to have sex, which led to a little conversation/argument. I tried to explain that there was no malice behind my words it was just a little joke, but he kept saying “I know you and I see it in your face, you’re bothered by it”. I just want more time with my boyfriend bc I can’t get enough of him I’m not actually mad or upset. I knew he had leave early (midnight) and I wasn’t even expecting him to stay that late.

Now we chatted a bit before going to sleep and I just feel like he is way too defensive about it, saying how he saw it on my face I was bothered, he said don’t make jokes about it if I’m upset and just say it as it is. I’m very lost and I don’t know get why he’s the one upset. I want to bring it up to him to stop reading into my face too much, if it was an actual problem I would’ve said so. I truly just meant it as a joke, but he’s insisting I wasn’t. I know he’s awake at the moment but he’s not answering at my texts. I don’t know what to do. How do I approach the situation without dragging it out?
