I got used to negative G's in my five years of skydiving.
They were the final part of every climb to altitude, prior to jump run.

I have a similar thing with my two kids. My daughter can handle a
steep turn, anything positive G's but push over the top and get her
light in the seat and she doesn't like it. My son however is the
opposite, he loves doing negative G things including making a notepad
float off his lap. He tries to get me to do that with mom in the
plane but I'm smarter than that.

I guess it depends on what the person expects, and what they enjoy.

Sometimes, you just can't tell...

I have always prided myself on flying as gently and conservatively
with all my passengers, especially my kids. My older boy has always
been a little queasy while I was flying. I tried all the usual
tricks- ginger, dramamine, electronic wrist band, and nothing really
took care of the problem. I let him fly straight and level, and he
was okay with that, but flying was too uncomfortable for him to be fun.

So today I took him up. It was an unusual day in the East, no
turbulence and excellent visibility. He asked if we could do some
"high G" stuff. I said okay, let's try some steep turns. He had
been following alone on the controls all along, but I took over and
cranked it into a 45 degree turn (I was pleasantly surprised as the
altimeter stayed pegged, since it's been awhile) and then rolled into
a similar turn in the other direction. He loved it! I said, okay,
see that long straight road, let's drop down a little and we'll do
some S turns. Then we climbed up and did some stalls, and then some
steep turns around a point.

So, we went through some basic but vigorous airwork, and he enjoyed
every minute, much more than when I was trying to act line an airline
pilot. In some rare cases, there is such a thing as being too
gentle. I guess the real trick is knowing when those are.
