My boyfriend has hiv, he touched his precum on my wound(bleeding) with his fingures continuously, can i get hiv from this kind of exposure?

Wound: The HIV virus is transmissable via any body fluid to any open wound or mucosal surface. So, yes, you can contact HIV from just such an exposure. He should always wear a condom and you should protect yourself as well. You both need some counseling on safe sex and precautionary behavior.

Yes it is possible: Don't involve yourself in behavior you know to be risky. You are playing with fire. Use protection condoms barriers etc. You should go and see medical health professional.
