Regarding..."my husband has quite a bit of discomfort sitting on regular chairs, just behind base of penis and in front of anus"
I bought a cushion...

It helps with harder straight chairs like a desk chair, but, yes, he'll be elevated a couple inches.

I stayed in the recliner for the most part the first couple weeks or so when sitting, or sort of half reclined on the couch, propped up on pillows.

Unfortunately for me, that sensation stayed around for months. Anytime I sat on a narrow bench at the gym I really felt it. Eventually it goes from light paint to annoyance to "huh, that feels odd" but only on un-padded straight chairs.
