I trust people in general to not harm me, for the most part.
Why? Because my intuition takes me out of bad situations.
Aside from that. I don't have a partner but I know I could trust mine because the psychic connection between me and the last person I liked made me feel when she intimate with others. So it's not like they could hide much from me.
I do for the most part. I trust me to get things done eventually and be reliable enough. I don't yet trust me to be everything I want to be superfast tho.
