Well - it does depend what you intend to do with it.

Too tight isn't really good for either partner IMHO - unless you're a pain freak.

Too loose still leaves the possibility of different angles - so I am told - and if it was a problem that you cared enough about, you can always do a bit of nip and tuck.

Your ex was either making the point that he had a big cock and you hadn't noticed enough or that he would have preferred you to loosen up a bit.
