I’m not sure if this is a thing or of something is wrong...

A few times when giving my SO a BJ his body for sure orgasms super sensitive after etc. but there’s no ejaculation? A few times it’s happened and he finished and I’ve had to ask bc there wasn’t any cum, he says yes and I just assume maybe he released while I was deep or already swallowing or just really mixed in the spit. But this morning I 100% know there was no ejaculation present.

There’s no doubt that his body orgasms, and I know my skills aren’t lacking nor is he faking.

I’ve not brought it up to him yet because i don’t want to embarrass him if this is like a thing? I’m pregnant 27w so I know he does cum but maybe doesn’t always produce semen?

It’s like he’s shooting blanks forreal. 

He’s a 36 year old man if that makes any difference.
