Okay, let me explain properly. This is the first forum I've been on, so I'm not used to explaining things.
My boyfriend and I are already in a semi-open relationship. My boyfriend is able to do stuff with other girls currently, as long as it is someone that I know. He has never been able to do much with them, or advance further, because I get jealous and change my mind, making them stop talking. We are both completely open to the idea, and my boyfriend has been looking by himself, but I keep changing my mind, so he has to stop.
Because this is my first real attempt at this, I thought it would be best if I were to help find him a partner or potential partner to begin with, someone we both agree on, to help me ease into the idea. It is not so much that I don't agree with it that causes me to change my mind--
I get worried that I will be left aside, or be number 2 to him, or worse, be replaced.
I get worried about what others will think, like I wrote above, people not seeing it as being "normal," which makes me think it's not normal, and so I make myself think it shouldn't happen.
