Still, this is nothing to be concerned about. Most strippers and most people do not have stds or HIV at that. You really had no risk at all from this kind of exposure. There is no transmission from hand to genital contact which I just found out from rereading your post, my apologies for my lateness.
This may be a possibility since this was a newly fresh cut which did bleed a lot as you mentioned in your post. Was this bandaged?
