 Tall Skinny San Pedro

I have a san pedro and the main cactus is about 4 inch diameter, but the top broke off so it wont grow anymore.
There are three smaller cactuss growing on the side but they are only about an inch in diameter but have grown to a foot and a half tall.
Is there a reason why their growing so skinny, or does the cactus girth just come with time?
The cactus has spent the summer outdoors and should have gotten enough light but it keeps growing tall and skinny like it did over the winter.

Long tally skinny pedros sounds like lack of sunlight. Maybe plant it in a spot with more hours of light per day.

Don't water it in the winter when it comes inside. Water directly signals the cactus to grow and how's it supposed to grow thick and strong without lots of sun?
It's also better to keep the cactus cold in the winter so it doesn't etiolate. Warm temps tell the cactus it's ok to grow. Cold temps tell the cactus to go dormant.
Warm conditions and water without sunlight = strong etiolation
Bright sunlight prevents etiolation regardless of other factors.

Thanks.
I did water it in the winter, so that makes sense.
Where does the cactus grow from?
The top or the bottom?
If it starts growing a normal thickness now, will it grow a fat base and then have a skinny cactus on top, or will the top start growing wider?
I'm worried that if it grows really wide on top of the skinny base it might break.

the top will grow wider.
I would let that grow for a bit till it starts getting heavy and cut it off where it started getting fat. I would then root that cutting.
the skinny spot I would cut off and root it and let it send out small pups for grafting to Pereskiopsis and let the fatter base pup.

Lack of sunlight, perhaps wrong soil.
