boyfriend too sensitive for blowjob?

I have been searching for answers to this question thruout the internet, but the answer is simply not to be found. My boyfriend and I have a fantastic sex life, and are very happy together... everything is wonderful except for one thing. He is too sensitive for me to give him a blowjob! I on the other hand, love giving them, but cannot.

His balls are even more sensitive, if i touch them (even lightly) in the wrong way, they can hurt... and it seems his dick is the same way... it is also very ticklish, and can make him laugh (of course spoiling the mood) if i touch it the wrong way as well... I don't really know what to do, and was hoping for some tips...

I was also wondering... am I the only one who has this problem? I'm careful to not use my teeth... and it's not just me, because all my exes said i was the best they ever had...
