Is it normal that my guy friend and i are into sex games on omegle/charoulette?

So I've been good friends with a guy for the last year and a half or so. We just get each other, and act a fool together and just totally be ourselves in any one on one situation. Lately, though, it's kind of been getting weird. Mind you, we're both nineteen and I will admit I am attracted to him and I have no idea of his feelings. Anyways, lately we have been going on webcam sites like omegle/chatroulette and visiting the adult sections together. We've done it so much watching guys jack off is normal! We don't even flinch. Now we are competing over who can make guys/girls do/take off/answer as many things as possible. Like showing their boobs/ass or being our valentine or asking if they want to have sex with us. I feel kind of weird, because we're friends but we're doing so many sexual things together. What do you think? Is it normal for two close friends of the opposite sex to basically play and compete in sex games with horny webcamers on the internet?
