AIO My bf wants to sleep with other people

My bf (27) and me f(24) have been together for 6 months. When we first got together we spoke about previous partners and experiences. I found out that I am more experienced than him. And he confessed that he had lost his virginity at 25 y/o. When I was dating my ex we explored a ton with each other. Different kinks, fetishes, positions. I discovered during the time that I dated my ex that I enjoyed watching my bf at the time have sex with another girl. We did that for a while. And I never had any issues with it. I believe it's called voyeurism (cuckhold) not to sure ?? When I did this I was between the age of 19-21 and I had only ever done this with this one specific ex. Now that my current partner and I have spoke about things we'd like to try or explore. I do not feel the same way I did as before. My bf had expressed to me that he would be interested in having sex with other girls while I watch but I don't know if I'm feeling a bit jealous or hesitant but something feels off. When I think about me watching someone else have sex i love that idea but for some reason thinking about my current bf have sex with someone else and me watching doesn't sit well with me. I think it's because my current bf likes to be more caring and romantic during sex. When l'm the opposite. I enjoy foreplay bondage, rough. I'm almost 70% sure that I feel hesitant because of the fact that I know he's romantic. He loves to make out passionately and after sex he loves to lay in bed naked caressing me while we hold each other and just talk about whatever there is to talk about. I feel that that's extremely personal and the times I've had a threesome or just watched my ex have sex with someone else it was none of those things. We just got down to it had our fun enjoyed ourselves and when we finished the girl that we had slept with would just leave. There wasn't any deep passion to it. And my current bf has admitted that the few times he has had sex it's all been romantic and passionate. That's where l'm conflicted. And I'm not sure how to go about this ???

PS I know 6 months is too soon to be talking about these things but it already happened I cannot undo what’s been done I’m just trying to figure out what to do.
