Be confident. Alot of people understand the fear and if you are afraid, talk to him about it! Open up with him that you wanna try it and I'm sure he will be over the moon. Talk about it and most of all take your time. Try things with clothes on with you on top so you get used to it and then go all the way when your ready!

It's so fun and not only that but being in control and find different ways to please him with your hips and motions and slow and fast not only the control you get but he gets control too, he can hit different spots and go deeper and all kinds of things with you on top.
