i need serious advice 😥

Okay so I need some advice ladies. I've been with my boyfriend for a while now & we live together. We are in a very committed relationship & we have an amazing sex life. I always go out of my way to fulfill him sexually & he loves it. But I have always known he wants to go to an orgy party/club. I've been super hesitant at first and I used to be so closed minded towards it bcus I feel shy or I feel like it'll be awkward for me since I don't feel like I would enjoy watching people have sex. I feel a little jealous too, of him watching other girls. I'm a big girl I have big boobs & chubby waist and big thighs so I'm not the most confident in my skin either. But he says he just wants to go watch 🤦🏻‍♀️ I feel like it's not a big deal at times and I'll be intrigued , but then sometimes I get to much into my head and I get super fucking jealous thinking of him touching another girl 😡 Idk, help! Should I go and try it? I just don't want to have issues in my relationship after because I get my feelings hurt easily. 😒

Have any of you ladies gone to a orgy club/ party with your significant other? How was your experiences ?
