Let's talk about safety!

I know this is a buzz ...... topic when it comes to sexual fun but hey, it's real life here. I'm just curious as to how you guys and gals eliminate the fear of stds or stis when it comes to hooking up with a new partner. Like I know myself, has never had anything. My wife caught something in her young years that fortunately was curable. What do you all do? We like the bareback thing because she cannot get pregnant anymore. She's free to take load after load if she wants. It is one of the big things that keeps her from really letting go and enjoying other men. I completely understand the fear. Especially after having an experience in her youth. Any ideas besides condoms?
