vaginapagina | resources for giving oral

Hey folks!

This isn't exactly a vagina question but I thought perhaps you all might still be able to help. Basically, after a long long long period of celibacy, it looks like I will be having a new sexual partner soon! I'm very excited, but a bit apprehensive about give him oral sex. It has been literally a decade I think since the last time I did that with a guy. I was wondering if anyone knows of any blogs or other resources where I could brush up on some basic techniques and stuff? (I'm envisioning something with a "teaching with diagrams" vibe as opposed to something with photos...but I will check out anything that anyone suggests!). Thanks in advance! :)
