Do many guys cum from having their balls touched?

[Anonymous]

I met an 18yr old guy at university (im 23). We were fooling around for the 1st time on the weekend at my place. I knew he was shy because when it actually came time to get down to business he was hesitant about taking his underwear off.

We just took it slow, lots of touching, kissing etc. He told me it felt great when I caressed his balls so I massaged them for a minute or so. It must have felt good because he had a huge messy orgasm without even having his penis touched.

Has this happened to many guys?
Is it normal?
I totally understnad. A guy once made me cum during foreplay from sucking my nipples. I just didn't think the balls felt that nice for men.
