Am I Wrong?

Two guys are best friends. I met one guy before I met the other, around my birthday this year I had sex with the first guy I met, this happened twice. His bestfriend and I started to hang out and chill but it was on some more brother-sister type friendship. Recently I went out for a weekend with the bestfriend , we ended up having sex.. It was in the spur of the moment-tipsy type sex but very memorable. Even though me and the first guy weren't together nor were we tryna be together I still feel kind of bad that I slept with two best friends , but the second guy I'm really feeling him, we actually hang out, and know each other like it might turn into something .. Am I wrong?
