What std or sti can you get from fingering someome if any?

General rules: These diseases are generally passed from one supportive environment to another. The moist environment of sexual secretions is the vehicle in which they are transferred. Unless the sexual fluids on the finger are passed to another moist environment, they would dry out & the germs die. Genital to genital transfer is the rule as intercourse includes prolonged contact of both to sexual secretions.
