Can’t get enough

So I am currently almost 27 weeks pregnant. At the beginning I was so sick I couldn’t function and sex was something that really wasn’t happening. Well now, it’s a completely different story. I want it all the time multiple times, doesn’t matter where we are. I feel like a psycho because the urge never goes away. Granted doesn’t mean I act on it because I don’t want my boyfriend to not want it anymore. Yet, I am also the one who initiates things most the time. He has always told me that he would never not want it and he is always down to do the dirty but I want it all the time and idk how to curb the urge. Any suggestions?
