I am having a problem with the veins on my penis.. Over night, after extended masturbation, my dorsal vein has become way more prominent and bulging (even when flaccid). I've done my research and I'm pretty sure this is penile thrombosis. Also, veins on either side of my penis have become more prominent (although they don't bulge) and a vein directly next to my dorsal veins has also become very prominent. Worst of all, 2 very thin, thread-like veins that are VERY noticeable when erect have showed up.. They run across the penis from left to right and are worrying me the most, they are red to dark purple.. They appear to be JUST under the skin and very weak and frail. It's been 3 weeks since the thrombosis and these ugly thread like veins are still there. I haven't had any sexual activity since, and while I believe the dorsal thrombosed vein will heal, I'm worried about the ugly thread like veins that came with it. I've taken ibuprofen everyday for 3 weeks and no sign of healing. I'm starting to get worried the veins will be there for good and sex will never be the same. I'm only 19.. Please help!
