Personally, my erections did not change.
My base is thicker than midshaft which is thicker than just under the glans.
PMMA goes all the way down. But each guy is different. Some guys have outcome is just what you mention. Others end up thinner midshaft. It depends on your personal anatomy and post op care.
Yes, they offer glans enhancement, but Dr. C has said that it provides minimal change. Nobody has an option for glans enlargement that provides substantial permanent enlargement. Not that anyone here has been able to find, anyway.
Post care is vital. You really need to pay attention to it for about 72 hours after. Give or take, this is about how long it takes the carrier to be absorbed. During this time the product can be moved, massaged and shaped. This is the time that it can also clump or move out of areas where you want it.
You can fly back in a few days if you want, but after 3 it is where it is. You aren\'t going to easily move it after this. Most guys stay at least an extra day, some 2, to go into the office and have them check things out. It is not required, but if it is your first visit, I would highly recommend it.
Keep in mind that this is, to a large extent, permanent. If you decide that you do not like it, the only way to have it removed is through invasive surgery. Read, research, ask questions and make sure you are comfortable with the possible risks and complications. It is certainly not a decision to be made lightly.
