Please Help Need Advice

Meeting up with an ex of 8 years ago. Have only seen him once in between and we both had crazy butterflies and we're blushing. Haven't kissed in 8 years. And only had Sex like 2 times in high school so it kinda doesn't even count. We're both adults now and want to meet next week for some adult fun , no strings attached. I'm nervous about not knowing what he likes or doesn't like ! Is it a bad idea ?
