I came into all this from PFS and have tended to have low cortisol, and I’m on 400mg of pregnenolone in the morning. That helped immensely across the board. I asked about Cialis because there’s a lot that can break about your dick. For me, and another poster here, thyroid meds (typically T3 / Liothyronine) make our dicks go numb when used in some contexts. If Cialis lets you boner then you know it’s more blood flow related, but if it doesn’t do anything, then the issue lies elsewhere. T4 before bed also helped me with a lot of things and is seemingly calming. T3 in the right contexts, like if I wake up at night, is also very calming.
When I came into all this my dick was fine, it was unbound thyroid meds, T3 in my case, that marked it breaking, but they help with other dire things, so I’m managing my dick around that at the moment.
