I happen to agree with Trebs. Still, I would say one needs extensive proof that his or her partner is trustworthy enough. If there's any sign at all that there may be dishonesty at all, then it's best not to trust your partner with that. It's best to keep using condoms unless your are as close to 100% sure as you can possibly be. Again, that is why I am extremely unlikely to ever allow it for myself. I'm scared of HIV and other STDs to the point where self-preservation is my top priority. Do I have trust issues? In fact I do, but that is my problem. Still, I'd rather stay safe, and that's the bottom line.
