Libido too high?

I'm feeling a little embarrassed but I'm 16 weeks and I can't seem to get enough sex πŸ˜•  When my husband is home I'm always on him to the point he's telling me no bc we do it so much! When he's not home I can't seem to satisfy myself with alone time. It's starting to not be fun anymore but kind of annoying. Anyone else feel like this or know how to deal with it other than cold showers?? Lol
