As I always say about my own condition, you can pull a cooked noodle, but you can't push it...
Other options post ED meds are:
Trimix dick injections just before sex. Can only get with a doctor's Rx from a compounding pharmacy, as far as I know.
Ultrasound shockwave treatments in specialized clinics
Penile implants that are firm enough to allow penetration, and, hopefully, the vagina completes the arousal.
Penis pump. A closed loop system that sends a saline solution from a reservoir surgically implanted in your groin to cylinder-like chambers surgically implanted in your penis,
To fill the chambers you squeeze the bulb containing the saline solution, which sends the solution to the chambers. To send the solution back to the bulb you press a valve button or whatever on the surface of the implanted bulb, which releases the solution back to the bulb.
My friend in Montreal, as I have posted before, did the injections for a couple of years. They worked reasonably well,
When they stopped working, he went for the penis pump, and told me it's amazing. He says his dick is harder than when he was in his 20's.
Because of his prostate issues the Quebec Health Plan paid the $30,000 cost.
None of them are my cup of tea...
