Sex positions?

So basically I am a big girl, and I have a high sex drive my boyfriend and I have sex like 3 times a day every other day sometimes we might not for like 2 or 3 days but I can't contain myself around him, lol. We do doggy, on top, and me on my back and that's about it what else is there to do? I'm a bit flexible and some positions we have tried are uncomfortable to me. Please help thank you xoxo❣️
