Rotdogs don't work, not as well as pooners say.
To make one thing clear - cis, straight women are not having sex with pooners. It is almost entirely bisexual and pansexual women. I also do not have a penis, as I am a woman, so I may get some things wrong about real penises. I did not have sex with the pooner. She is an ex-girlfriend who transitioned some years ago and was happy for me to examine her "new" penis.
The one that I will be writing about was a
ALT Phalloplasty, where they skin the thigh. She admitted that it had taken 4 years for her to get to this point, mainly due to complications. She had also had medical tattooing and an erectile implant that was a snap in type - I am unsure if it has a real name.
The penis is colder than a regular one, and the moment you hold it in your hand, you know that it's not a real penis. There's also something very uncanny valley about holding one physically, as there's no sensation from light touches, unlike a natural penis, and obviously no foreskin or outer layer of skin. It feels very similar to gripping your forearm but without the feeling of blood pumping through it. If you try and jerk the penis, then there does feel as if there is something physically holding it back, again, grip your forearm and attempt to jerk it - that is exactly how it feels.
The thigh scar never seems to heal fully; it's extremely rough and has hardened raised bumps.
I have no direct experience, but from less picky women, I have heard that giving oral to a neophallus is very disconcerting, as the penis does not move. There is no twitching, no feeling of it getting harder, or even pre-cum. There is also a marked lack of sensation for the owner of the penis.
Actual penetration is another story:
There is an audible snap when the erectile device goes into place. It isn't a connecting rod like a hinge but rather a semi-flexible rod that can be snapped to stay rigid. She mentioned offhand how it had failed multiple times, and she had to undergo surgery to have it repositioned in the neophallus. If you've ever messed with
a pipe cleaner then it's basically the same. The tip remains squishy, as the device is only within 3/4ths of the shaft, from roughly half an inch from the "base" to just before the "tip".
The "balls" tend to hang quite limply, if they hang at all. They aren't attached to the skin that functions as a "scrotum", which leads to the "testicle" just kind of floating around inside the scrotum. This was mildly amusing with the owner of the penis not being aware her testicles had shifted onto one side, as she couldn't feel anything. They seem to just be plastic egg shaped implants, they are hard and obiviously don't react to the environment, and it doesn't ejaculate.
Penetration is extremely difficult, as the phallus struggles to insert into the vagina. It doesn't really spread the vagina, as the vaginal opening squish the phallus too much. The rod only makes the inner shaft rigid, but the actual phallus remains soft and difficult to guide effectively. There is little to no sensation for the owner of the phallus, and the feeling for the person being penetrated is uncomfortable.
Most rotdogs are extremely large, and as such, many owners seem to be disappointed when a vagina cannot or struggles to accommodate it. The woman I know mentioned how women who "weren't aware" had expressed a desire not to be penetrated by it. There is also a rarely mentioned issue by phallus owners where they are unable to clean their "urethra" effectively. There is a small hole on the underneath (which seems to be a failure point for the phallus), and there seems to be little to no post-surgery advice for the urethra.
It was mentioned that a
cotton bud should be used to clean it. This is not effective, and the phallus tends to stink of urine, and get strangely greasy.
TL;DR - they don't work.
