New guy I’m seeing is too tall for me?

Hello, I (20 FTM) recently hooked up with a guy (19M) and had a pretty good time, so I would like to see him again. The only issue is size. Im 4’11/5’0. My previous partner was 5’8, so I roughly had no issues with him. This new guy is 6’2 and heavier than my previous partner. It seemed like we struggled a lot for him to stay in and every position he wanted to try, I was too small for so he kept slipping out. I like him so I want to make things work, is there anything we can do to fix this? Missionary was fine but I felt I was being smushed into his chest. Any advice appreciated, thanks!
