I am 52 and have undergone menopause, without any touching, when I get aroused there is blood in my natural vaginal lubrication. When your bartholin's glands (located slightly posterior and to the left and right of the opening of the vagina) are not well aroused, they could fail to produce the mucus which is intended to make your vagina wet which could cause friction that can lead to the bleeding. Or as above, some women's vaginal lubrication tends to be bloody at times although if it has never happened before its better to get checked by your specialist.
