I was just wondering how long after being fingered, or after sex, should I be sore for.
Usually i'm sore for about 2 days after a guy goes down there. Is that normal?
Also, it's very hard for my boyfriend to put his penis in me. We are having a lot of trouble. Is there anything I can do at home to try to stretch my vagina a little bit? I'm a small girl btw.
I do have a internal vibrator which I dont use much...should I start using it more often?
Thanks 
Well, demon pretty much said what I was gonna say. lol.
But I'll add that I'm small down there too and I've found that a vibrator (and using tampons) has helped some.
I'm also dry down there (even if i'm "dripping" so to speak) so I have to use a lot of lube and that helps with the insertion and pain I get. I use astroglide as my main lube, and I've found that the new silken secrets helps as well because with those, you're able to "squirt" the lube in there.
And yup, soreness is normal.
I was sore for a few days after my first time and then when I tried anal for the first time, I was sort for a day or so.
And really, the best way to take care of the "stretching" thing so it won't hurt as much, is, well, to do it more often.
Sounds easier said than down and of course, a lot less painful, but really, it's the best way.
the vibe should help, also make sure you are lubed up good.
a few days of soreness is normal. depending the activity.
especially since you guys are already having difficulty w/ insertion.
