Is it normal to do sexual things with your male bestfriend?

I'm a male, and when I was younger I had a very good bestfriend. As young teenagers we both learned about masturbation naturally and were curious. We both did it alone, then began to do it together. Within a short period of time, we would do it to eachother, and even give one another an occasional blowjob. It was tons of fun but we never seemed gay. We both went through numerous sexual female relationships during the time, but every now and then did sexual things with eachother. I almost stuck my dick is his bum when he was bent over once but he wouldn't let me, and I saw some poo. We never saw eachother after that. Am I normal? Is this normal? People say I'm fucked!
