under what conditions does a vagina not feel good

i was at the italian deli thinkin about old ladies.
i wondered: what would it be like to fuck them? bad? ok? good? gross? nasty?

then i was like: if gross, how much of that grossness just comes from it being attached to an old lady body?

so imagine you had a woman with a pretty face and fine body

but she had a pussy that you could hot-swap with other ones

so you put the old lady pussy onto the hot woman and put your peener in that, hard of course.
hows that feel?

does smell come into account?
does an old lady pussy smell bad no matter what they do? or can it be fresh like a young pussy?
