I can’t tell if my yucca is okay?

I got him a few? Years ago now, and I don't know if I'm being an idiot or not. The stem is slightly squishy, but I don't know if it should be 100% rock solid or if that's acceptable. The leaves also look kind of droopy, and since I got it, it's not had any pups or anything- I took a cutting last year from the top and even that still hasn't had any new growth, just calloused over. The cutting I took from it also doesn't seem to have grown much, though that one has more sticky-uppy leaves (scientific term)

I'm just confused- it doesnt look dead but I can't imagine it's healthy?

I watered once every two months (or less) over winter, and once every few weeks from april-september. It sits by a West facing window or under a grow light. Pot has drainage, soil is a 3:1 mix of perlite and regular potting soil (is that where I'm going wrong?)
