Needs more options

Pretty solid implementation, but we need more options. May I suggest:

$Result .= apply_filters( 'penispress_penisstring', 'Penis ' );

That way, I can write my own Penispress plugin, eg

function bbg_maybe_vaginacize( $w ) {
    if ( rand( 0, 1 ) ) {
        $w = "Vagina ";
    }

    return $w;
}
add_filter( 'penispress_penisstring', 'bbg_maybe_vaginacize' );

Thanks for considering! Looking forward to further development on the PP (pee-pee) platform.
