Buddypayne, I had an implant before prostatectomy (RP will happen soon, actually). But I think I can answer most of your questions

What has your experience been like after being implanted?
Some of my questions/concerns are.
1) With no glans enlargement how is sex?
The implant should not affect glans engorgement/enlargement, so sex should be about the same to your glans. The only difference is that that after you orgasm, your glans may deflate while your erection (supported by the implant) remains. So you may have a soft knob atop a rigid penis.
Of course, the spongiosum tissues (responsible for glans engorgement) may not deflate at all since the erectile tissues usually responsible for erections (now replaced by the implant) get their blood flow from a separate and independent system the blood flow the engorges the spongiosum tissues of the glans.
So, absent surgical damage during the operation (rare), you should get glans engorgement as you did before. And it MIGHT continue or return after orgasm if you keep going with stimulation.

It might. But look at it this way. Normally, a penis fills with body-temperature blood and that blood is trapped (in the erection) by stopping the outflow. That blood-filled penis is exposed to outside air which begins extracting heat from the penis. So, an erect penis starts out hot and cools because it has a lot of surface area losing heat.
An implanted penis fills wit body-temperature saline solution trapped in the erection. The penis begins losing heat to the outside air just as the blood-filled penis did, so begins to cool.
The idea that an implanted penis is colder than a blood-filled erect penis flies in the face of simple thermodynamics. There is the matter that the blood-filled penis DOES HAVE some exchange of fresh, body-heat blood does suggest that the natural erection will be warmer than the saline-filled erect penis.
So, I will suggest that the implanted penis may be a bit cooler than a naturally erect penis, but not by much.
Also, there is the idea that if you keep up a lot of energetic thrusting in a vagina, the friction may generate more heat and make the penis warmer.

Not 100%. But there are two salient points. It feels a WHOLE LOT more natural than sex with a limp penis or an erect penis that I have to worry about every second.
buddypayne wrote:4) Do you have any regrets?
No regrets, not even (as most men report) a few moments or days immediately after the operation asking themselves, "What the fuck did I DO to myself?" I researched ED and its treatments thoroughly before taking the step. I do not even regret the time I took to find a good surgeon (more than a year). I only regret not mentioning my ED to my primary care physician earlier so I could have started the journey earlier. Out of embarrassment and uncertainty I kept my ED problems limited to myself and partners and did not mention it to any medical experts for decades. If I had started oral medications when I first would have qualified for them, my path would have surely been different.

Explore all less-invasive treatment (ignoring the snake-oil and magical crap) before taking the step of an implant. And select a really good surgeon in whom you have confidence. I found one who LISTENED to me and I was convinced would hold my best interests as the most important. Dr Eid wrote to me this, "Find a surgeon in love with his craft." He went on to say that such a surgeon will do all he/she can to provide the patient with the best possible outcome.
