I haven't done head before, but I recently gave my first hand job and that was intimidating. But I am so glad I tried it anyway! I think sometimes you need to just push yourself to do things new. I've heard from LOTS of people that giving blowjobs is fun. So I would say try it at least once. If you don't you might regret it later... As for technique I believe you just pretend the end of the penis is a lollipop. Imagine it's your favorite flavour!
