Sounds like your BF has a but of an attitude. First, dont; let him make you feel inferior because you supposedly dont know what you are doing and he won;t communicate. That is his problem.
Second, Dan and Jen have a GREAT series on blowjob tips on this website you should check out that will really help. One of the biggest mistakes women make is presuming guys like how women do blowjobs in porn. Hardly. It's more varied than that. One strategy if the penis has too much girth is use your hand for stroking and concentrate mouth action (but NOT exclusively) on teh head, especially just under the urinal opening. see teh tips for more details.
