Bj tips

Hey ladies! So I have been seeing a guy recently and it’s been a really really long time since I’ve given a blowjob to a guy. He’s a lot bigger than the past two boyfriends I’ve had and I was hoping that I could get some tips on how to make it better for him! I started to give him a blow job last night but it’s been so long and I felt like I was doing something wrong and he said it was completely fine and that he understood so he stopped. I just want some good tips so that I can “blow his mind” Any tips will be greatly appreciated!
