I think this falls into 2 categories. I’ve just started HT now for the rest of my life as I’m incurable PSA 990 at 53 yrs old and 6 yrs post surgery. Only been on it 3 months but my libido at the moment is still very much there as is EF. Problem for me is that I’ve lost the ability to orgasm at all mostly which is quite frustrating. It’s extremely normal and unavoidable to lose libido but tbh my libido was stupid-high in the first place , hence why I still have some , and also I’m younger than you ? Not sure and no offence.
I guess things like massage need to take the place of natural desire.
