I’m not very experienced when it comes to different sexual positions, I’m in a long term relationship with my partner and he’s perfect... but When we are intimate he enjoys sometimes if I’m on top ... but I don’t feel confident at all!

Any tips or advice to help? How to position myself? How best to move?

He always greatly enjoys this and says it’s really great and attractive but I worry I just don’t feel confident and hence I don’t enjoy it and feel super self conscious?! Tips??
