Sex tips for shy girl?

Maddie
i'm still very new to having sex, and the guy i'm currently sexually active with is very expirenced. it's been great for me, but i've been worried that i'm not able to satisfy him due to my inexperience. it makes me nervous to take risks in bed to satisfy him. 
any tips to get over my nerves?
what are some small things i can do to turn him on but that will be less scary for me?
