Sex positions? TMI!

Hi everyone, so your girl is in need of desperate advice! lol my Hubby and I love sex, but we do the same positions all the time, missionary or doggy...and we haven't tried anything else, mainly because my Hubby's "you know what" is on the smaller side while he himself physically is on the larger side. I am thicker, mainly carrying my weight in my thighs and I am also 20 weeks pregnant. Do any of you know of any positions that we can try out that won't make my Hubby frustrated and won't make me hurt?😂 or have dealt with this before?
