Randori tips

I had a randori session with my partner, who I usually train with (Orange belt) But I wasn't allowing myself to be throw which made me a more difficult uke, and he also wasn't easily thrown, I got close on one thrown but that was all that I got close on. (He got close on one De-Ashi Harai a couple of times but that was it). What is some better tips to ensure me and him both get in good throws and falls/Get the best out of our training session?
