Thanks for posting your query.

The symptoms you are experiencing since 4 yrs seem like priapism which is painful penile erections due to trapping of blood in the blood vessels of penis. It can be due to numerous causes like blood and vascular disorders or age related atherosclerotic changes, etc. If not investigated and treated in time it can lead to decreased blood supply to penis head & erectile dysfunction in future like what you seem to suffer.

Other possibilities can be age related cavernous body degeneration where the elastic tissues of penis which expand on erection are replaced with scar tissue which cannot expand and cause penis shrinking and inability to attain erection.

Adding to the other problems, the decreased testosterone hormone in aged males may contribute to the sexual dysfunction.

So considering your symptoms you seem to have a significant degree of penis shrinkage as urination is also affected, I would advise you to consult a urologist to confirm this possibility and start appropriate treatment to prevent further damage and permanent erectile dysfunction.

Hope I have answered your query. Please accept this answer if you do not have any further queries. Should you have any additional queries, I will be available to help you further.
