I know this feeling. But first of all - you need to loosen up and don’t feel too anxious about it! Your guy just wants you to enjoy it too. And after more practice, you will absolutely love it and love that it is very enjoyable for him too.
A basic tip is basically, the tip. The penis’ head is very sensitive - with more than 4,000 nerve endings! Just get your lips and tongue all over his head, corona and banjo string; he will go wild! Just experiment and have fun (and lots of giggles) whilst trying to please him. And if you’re still unsure, ask him what he wants. That’d turn up the temp ;)
Girls have 8,000 on their clitoris by the way.
