Biden is a sex compulsive. While he likes all young girls and wives (except Black), he is particularly attracted to very young White girls. Even though he is much too old to actually perform sex as you and I think of it, still his compulsions drive him from years ago. Who knows how many women and girls this pervert has coerced into forced sex throughout his life.
Again, it is noticeable that since Biden sniffs and gropes every female (young or married) within his view, he has NEVER hit on a Black female, of any age. Maybe he did at the pool when Corn Pop showed up to kick his ass for perving on little kids, but not since then.
