How to suck an Uncircumcised Dick

Okay...ladies let's be honest!!! An uncircumcised dick is not the most attractive thing. And I'm never too sure on what to do with one. I have been lucky enough not to have much history with them... but recently the guy I have been dating has an uncircumcised dick. When I first felt it I was scared cause it was huge... but I then noticed it was uncircumcised and I got more scared! I honestly love sucking dick and I must say I am the shit at it... guys damn there cry. (Pat on the back) Although when I sucked his dick... I felt like I knew what to do... I kinda just pulled the skin down... and went to work lmao. But I feel like there is other tips out there that some of you ladies may be able to share. Please please please be as open as possible!!
