Weird massage experience

A few days ago I went to a massage place in Shenzhen, a place I've been a few times before. It's a chain that's decently expensive and on the higher end. When she asked me if there was any part of my body that was sore I told her my core was since I had worked out yesterday. The place has you change into a pair of shorts for the massage instead of a sheet. The first half of the massage goes uneventfully, but when I'm facing up and she starts massaging my legs she would go pretty far up, pretty much barely brushing my balls with her fingers each time. She would also brush past my dick a few times when she was using her elbow to get some knots out. Once she started working on my core, she kept brushing on my dick. At this point it was enough to be noticeable but I didn't say anything. Toward the end of the massage she starts to go under the shorts, basically massaging everywhere except my dick and balls, but brushing against it consistently. Pretty much doing normal massage motions but pubic area very very close to my dick. Eventually I came, and she wiped it off and finished the massage.

I didn't really mind the whole thing, but I found it super weird. Just wanted to see if it was normal for someone to massage you basically in the pubic area and under your shorts when asking for a core massage, and if not why she would want to do that given there was no communication or money involved, just a regular massage.
