I'm very pleased with my very average clit (neither a micro-clit or huge). And ....

..... yes technique, atmosphere/mood are big factors in if I cum, how fast and how hard . Sobriety for me doesn't play in much at all because I very rarely drink wine or any other booze and if I do I keep it super light.  
I'm unfortunately familiar with some gents in the past having "liquor dick" but i've never experienced "liquor clit" myself or with a lady friend i've played with (and we've had drinks).

I do not believe the size matters in terms of sensitivity other than it maybe easier for your partner to navigate if it is somewhat larger .
For sure mood , positioning , technical approach all have an impact. Sharp stubble rubbing under the hood has to be the worst for me though, it really hurts, feels awful and is difficult to come back from. Chemistry between the two people i find to have a huge impact as well . Pollie Amorous

To me if the hair is stubble and sharp  it is like needles , many of them being pressed into the most sensitive part of my body making it sore almost like a tattoo on your clitoris , not pleasant honestly . However a soft tongue is very different . Pollie Amorous

They were so big and got so hard I could easily feel them when I let my fingers do the walking.  In both cases these miniature hard-ons seemed to give the ladies extreme pleasure.  Don't know if that's representative or not due to the small sampling size.  I'll keep looking for suitable research subjects to add to my database.

I am very pleased with my size...

Not to large yet not to small.  Seems to fit my pussy nicely lol  
as for orgasm? All of that depends on what my mind is ticking on really so none of the size stuff matters. I guess I'm one of those people that it's not only a physical thing but also mind n soul thing to get me off like a rocket. I can say with age it has definitely gotten way more sensitive!  
Now since I'm bi sexual,  I love to see a nice swollen n rather large clit. I know that really wasn't the topic but....since we are on the clit subject lol
Hugs and kisses
TL

there are certain looks I like better.  but once one is there, I like it all.
