I know about the dangers of switching holes without using a condom, or sharing rubber toys without using a condom.
However, what if I only use it on myself, and only vaginally? And will never share it with someone else or put it in my ass. Do I still have to use a condom each time?
I also know about the risk of re-infecting yourself with an STD, but I'm clean, so that shouldn't be a problem, right?
