Some women have labias that are very large and conceal the clitoris within them, so to find the clitoris you have to gently work them labia back with your thumbs while licking between them.  You can sense it with your tongue by the warmth and the zesty taste.

I sort of like it because it's a bit of a challenge.

It's there, believe me.

Re: Daty: Has this ever happened to you?

The last lady i was with,,,,u could hang your coat on her clit,,it was so large and prominent.
YUMMY!!!!!
Hell,,,it was almost as big as my dick,,,LOL!!!

Each woman is individual...  viva la differance!  Also, their bodies change during the arrousal process.  I particularly enjoy pleasuring a woman & watching her breasts enlarge.  Well, it happens down stairs too.  Go slow, be gentle & let her guide you.
That said, my most recent experience, I just seemed to be out of sync with her...  I know she did not get as much out of it as other occasions.  I feel a little guilty because I got my full pleasure when she did not...  she's ok with it, but I know I can give more.
Next time,
skb
