Boyfriend knowing about past FWB

So before my boyfriend and I got together, i was a slut. not like in a bad way but i do have a pretty high number. when my boyfriend found out about that number, it made him uncomfortable. partly because of how high it is and partly because of how he found out. but we've moved passed it and everything is fine. But so theres a guy I was super good friends with all throughout high school and we ended up become friends with benefits after graduation. There was absolutely not romantic feelings though. The benefits were purely physical. Of course we love each other but truly in a friend way. Absolutely no romantic feel from either of us. And when my boyfriend and I started seeing each other, I told this friend and we obviously cut off all benefits. So we're still friends but nothing else. My question is, should I tell my boyfriend? Part of me thinks he wouldn't want to know but I'm concerned he'll find out and be hurt that I was keeping it from him. I dont know what to do. I also dont want him to be uncomfortable with this friend and I still talking. I would never cheat on my boyfriend but I would completely understand him feeling jealous be use I would if shot was reversed. I dont want something like this to effect our relationship but I just dont know how to make it not be a problem. So should I tell him?
