I'm an equal opportunity finger-receiver until someone proves to me that they suck at it LOL. Some people do that right off the bat. And definitely no long/sharp fingernails in my pussy, although I usually have an emery board to offer if it's important to a guy who has long or sharp nails.
I love a good finger inside me tho! I AM ridiculously tight and even two fingers can be way too much for me. Finger have bones in them and are harder than cocks. Two fingers is often an uncomfortable stretch for me, depending on the thickness of the fingers involved (from most men it's too much, unless they warm me up really well first). One finger is about as much as my pussy will accommodate without some warm-up time. So yes, most guys immediately comment on how tight I am as soon as they insert a finger. A little slow, gentle, subtle massage with the finger combined with some skilled DATY or my own masturbation gets my juices flowing and leaves my pussy begging for some cock. It doesn't make me orgasm, but I love teasing my pussy with a little sensual finger action and am not afraid to tell a guy how I like it. I appreciate the warm-up to get my pussy open and ready for a cock. Otherwise it feels REALLY tight when a cock goes in there if I haven't been warmed up with a finger first. Which is OK, but definitely requires some very slow, minimal stroking for a few minutes until my body opens up and releases its vice grip on the organ inside of me.
(Did you know that a woman's internal organs rearrange themselves while she's having sex to make room for the cock? I only know because with me, it's a particularly noticeable internal shift during the first 2-3 minutes of sex.)
A lot of guys also love my pheromones and want to put their fingers in me so they can pull out my pussy juices and lick them off their finger, or let me lick them off, or maybe we can both lick off my pussy juices and make out in the whole mess of pheromones. That's pretty fun too!
