Opened Relationship Sorta

Since my boyfriends sex drive dropped, I've been wanting to ask about opening our relationship. Besides just being able to find a man to satisfy myself, I thought if he could have another girl over occasionally, that it'd spark his interest in me again.

I did ask him about if he wanted to see other women on his own, but he said he wasn't interested. The only thing he ever really brings up is me bringing another girl home for the both of us to share, and as hot as the idea is, I know I wouldn't be the focus of either of them, and I wouldn't have a great time just watching my bf fuck another woman while I sat there like a cuck.

I know there'd never be a way he'd let me see another man, so I aksed about if he'd let me see other women on my own and he said yes. My experience with women sexually is pretty limited, and I know I can find a man easily enough, but I'm not having any luck with women so far, and I'm not sure that will change. Starting to wonder if my sex life is just over now unless I'm fantasizing about things that could never happen :(
