Sex position help?!?

Hey,
So I love sex with my boyfriend. It's amazing and loving and just great. Lately I've noticed that he's been getting bigger and sex in our regular positions has become pretty uncomfortable. I'm a fairly small girl and he's a lot taller than me and just bigger in general so it makes it difficult for me to be on top. 
Any position tips? Google failed me on this one 😝😜. 
Thanks a bunch!! Xx
