Nothing wrong whatsoever with a father and son relationship that's more physically affectionate. If we can hug and comfort them when they're a toddler, we can hug and comfort them when they're thirty! They are always your child even if they're an adult.
So sad. I do want to point out the men get raped as well, by both men and women so it's not just about "evil men" and "helpless women" although it's usually the case. < it just said rapists, without pointing out genders at all.
