I am having some problems with me penis. Three if I am honest. 1, I have a lump on the side of my penis head which started out looking like a blister but after masterbating I think it popped and clear fluid and blod came out. its been 2 days since then and its not bled or pussed but it is still a hard lump. 2, My girlfriend and I went on a long weekend holiday and I think I bruised above the penis (the pubic area) which I am guessing could have caused the next problem. It has been over a week and I am still experiencing pain in this area. It did have swelling at first which seems to have gone down. 3, when my penis is erect, from the base of my shaft (on top of the penis) to about half length a nerve (I think) or large vein is quite prominent. I only noticed this today but it seems to be a knock on effect from the bruising above the penis since I had sex last night. I was wondering if I could have contracted something off of a toilet, but after researching I found it is near impossible. Neither of us have had another sexual partner and have only been with each other for the last 6 years so I am guessing STIs are ruled out. So I was wondering if you possibly knew what this all was?
