I was with a girls too and when they tried it was quite interesting, feeling lips around base of my dick.. but I always took it mostly as sign of submission and being really into it and trying it out, even if it might be uncomfortable. I'm quite big myself so it usually only worked before I got fully hard...
But passionate sucking feels great (no matter on what end of the dick you are), most nerve endings are in the frenulum and head, so that's what matters. Going in and out fast while stimulating it with your lips and tongue feels great. It's not that hard to do so, I'm sure you have done a good job :)
