Sex while Pregnant😳😳

Ok so I'm barely 16 weeks and our little Frijol seems to get right in the middle of our lovemaking. I'm where I want to have sex constantly. 😊 but can find a comfortable position besides side straddle. I try being on top but I can't move the same. This is our first baby together and even though I already have 2 girls from previous relationships I was not sexually active in either of my pregnancies. Advice ideas😁 please and thank you.
