Help am i overthinking

So my boyfriend an i have been together now a year on February 10th. Lately I’ve been kind of feeling like we don’t have sex as often as we used to. There’s oral involved but it seems that’s all he wants to do. I try to let him know i want more and try to slow things down but never happens. Maybe i need to actually be more vocal about it. I kind of think it’s maybe stress he has a lot going on with his job being on the line. I’m just not sure of what to do or how to go about things. Can you guys help a lady out ?
