does sex with a super thin guy hurt?

Ive only had two partners in my life and both were very chubby. I loved their cushiness during sex. Although holding my legs that far apart got pretty strenuous on my hip bones otherwise everything was great. I loved my hman pillows. But now I'm with the complete opposite, he's a beanstalk with no meat whatsoever. I haven't slept with him yet so I have no idea what to expect, is it going to be like being cut in half with a razor sharp pelvic bone? Lol forgive me, i don't know. All I know is guys have told me they thought really skinny girls were hot but once they got in bed it was like a "sack of bones" and they couldn't stand it. And honestly I dont have a lot of cushion myself so I depend on the guy bringing the cushiness. I haven't even gotten to cuddle him yet so I haven't tested his pillow potential either. Please dont judge I would still sleep with him even if it ends up being horrible cause I love him, I just want to know what to expect. What is sex like if you're both really thin?
