Uncircumsiced penis tips?

So the guy that I'm talking to told me that he has an uncircumsiced penis and I've never experienced anything with one before. What are tips and tricks to giving blowjobs to an uncircumsiced penis? 
Yes I know that it's the "same thing" but one just has more skin, but I've heard that they're more sensitive and there are things you can do with an uncircumsiced penis that you can't do with a circumsiced one. 
Thanks for the help!!
