I don't think once every other day is going to negativity effect you in any way. I have done more than that most of my adult life. It has never been a issue. That said, I have always had a high sex drive. It has slowed down a bit but even now I orgasm almost every day whether that is from sex or masturbating.
I have not. I gave up and just went to the home page in Chrome, used the three dot icon to open the menu, and clicked "Install App". It puts an icon in your apps list that is basically a browser window with no menus. You can even change the icon and name. It shows up as a separate entry in your open apps too.
