I cannot imagine a scenario where I would tell my husband anything about previous lovers' penis sizes. In fact, I don't think I would mention their anatomy at all except to mention they were a shithead, asshole or some other physical/mental deformity. They may even have been a prick, but I won't mention the size of the prick they were. I may have said enormous prick before, but that was hyperbole and not at all physical.
