I had sex with my wife a few weeks ago, and during this time (she was on top), there was an instant whereby she thrusted just a fraction too hard which caused instant pain to the shaft of my penis. After I re-corrected her position, the pain dissipated and we carried on as normal and everything carried on working fine.
A few days later, I noticed, whilst in the shower, that, when looking down and feeling the shaft of my penis, on either side on the underside, it kinda feels that there is hard tissue, almost like I can feel bone inside?! It's quite strange as I can feel this on both sides (about 3 to 4cms from the body, going outwards towards the tip).
Its not swollen, does not hurt, is not visible (either when penis is erect or flacid), nor is it discoloured and all penis functions are normal - it's just that I can now feel these 2 strange 'bone' like hard pieces if I squeeze me penis on either side, with my fingers (again, lumps do not hurt), so I am really at a loss as to why these have suddenly appeared and if the penis is damaged at all?
After further researching my symptoms online, I have discovered that my symptoms do actually match Peyronie’s disease (healthymale.org.au/mens-hea.... I know searching the internet isn't always a good thing, however, when reading through that link, the following does indeed sound like what I am experiencing:

What are the symptoms of Peyronie’s disease?
Peyronie’s disease begins as a small swelling or inflammation, which hardens into a lump on the upper or lower side of the penis. It usually develops over time, but sometimes appears very quickly.
In most cases, you can feel a hard lump at the point where the penis curves.
Peyronie’s can be painful, reduce flexibility, and in most cases will shorten or create a bend in the penis when it’s erect. In some cases, the shape of the penis changes so that there’s an hourglass deformity or constriction to one side.
In the early stages, you might experience pain when getting an erection. In mild cases, where the lump does not cause the penis to bend very much or at all, it will only have a minor effect on how you experience sexual intercourse.
However, moderate or severe Peyronie’s can make sexual intercourse impossible because of the shape of the penis, or problems with getting an erection. In some cases, the penis only becomes hard up to the area of the scar and stays flaccid (not erect) past that point.
You might notice Peyronie’s after an injury to the penis. People with Peyronie’s often describe hearing a loud ‘crack’, followed by pain and bruising, although in many cases you might not remember any injury happening. Usually this type of injury leads to swelling which becomes red and hot, and will heal by itself within a year. Sometimes, recovery takes longer, and scarring can happen.
END QUOTE.
I will say though that I experience NO pain whatsoever, both when not erect and when erect and all penis functions are 100% normal. It's really only the lumps (which are not even visible) which are the symptoms. My penis also does have a downwards bend in it, which has been present all my life but has posed no complications due to this (neither when going to the loo or nor when having sex).
This condition isn't also widely known with no firm answer as to what causes it - treatments also limited on the NHS. I haven't yet seen a GP as I need to call on the day for appointments so getting one is not easy but I am guessing I will be referred on to a more specialised dept.
I am not even sure if this is worth progressing if its posing me no problems....?
