How was your first BJ?

If a guy has never had a ******** before, does he know what to expect? Like it seems like the first time a guy gets one, wouldnt it be good no matter what? And then just as he recieves more and more he knows more what he likes and gets more ytical with it? I've given a few..i wouldnt call myself and expert, but this guy im with said hes never had one, soooo guaranteed success? Haha im nervous and im just hoping it would be easy since he hasnt had one before...is that the way it is? Please share your experiencessss
