can a new 1cm*1cm abrasion an the penis shaft be a way for transmission?
Not if it isnt a brand new cut, and even if it was it wouldnt have a great impact on your risk.
You men that, if there is a cut in penis, it is not important?
In so far as I am aware, and other posters may be happy to give you a more definitive opinion, there are differing views as to whether transmission is likely through this kind of exposure.
My own view is that, given the already relatively low transmission rate in penal-vaginal intercourse, and the covering of the urethra, there is no risk of transmission here.
