it certainly can, but not all girls lose interest in sex after being spayed. in my late teens/early 20s i had a collie girl who was spayed but had a litter of puppies at some point. apparently that was enough to retain interest. i didn't know anything about cunnilingus back then, sadly, i think she would have absolutely LOVED it, but we enjoyed outercourse a LOT. if you're gentle and use lube, you could probably get several different sizes of dildo and stretch her out enough to accommodate normal sex with her, but as i said in a previous post, go _slow_ and watch for any signs of discomfort or distress, and stop if you see either.
