If I were you, I would lock up the straights when one of your girl friends is visiting-just to be safe.....An old Filipino friend of mine told me it was reasonably common for Filipinos (not Filipinas) to shave with a disposable blade SR about 40 or 50 years ago, particularly with poorer Filipinos, as it was the cheapest form of shaving.
As for my girlfriends, they are fascinated to watch me shave but are scared to even touch a SR.
Have you ever heard of Lorena Bobbitt?
Also, considering your situation, I would strongly advise against adding a girlfriend with Italian heritage!
