On the bus one time....

Ok, so I'm a guy that's in high school now but when I was in middle school, the buses would come to the high school I'm going to now. So, there would be kids that were in 6th grade sitting next to seniors. I happened to be in sixth grade and I would hang out in the back with my friends so the bus driver couldn't see what we were doing. So I make friends with some insecure high school juniors, and one day I'm sitting next to one of them and she is talking about how she never seen a man's genitals before and there were three others that agreed. I just happened to be the only guy back there on that day, which didn't really work to my advantage. They asked me if they could see mine and I didn't really have a choice to say no because they started unzipping my pants anyways. As I was sitting there, three high school juniors were touching me on my private, and they gave me a hand job but they never really like gave me a blow job or had real sex with me. Is this normal?
