Thanks everyone for your replay and Thank you KC43 for your reply. It made me feel much better. :)
After I wrote this thread I thought about it a bit more and the only trust I have to think about is the one with my partner and it is solid. She is an adult and I trust her to make the best...
I am fairly new to polyamory so there have been a few bumps in the road.
I have two partners one who has play partners that have come before me and one who up until very recently had no partners.
I have never had any trust issues with the ones that have come before me with the first partner...
