Question: Hi. I have a strange vein-like line running basically on the bottom of my penis shaft from the scroddum almost to the penis head. it almost looks like a scar as it's darker in color, almost like a dark red under the skin. It's been there for years. I now within the last week or so have noticed a bubble-like almost blister that looks to be filled with fluid, about the size of a pea. upon closer inspection it appears that this vein has an opening towards the top of it close to the penis head. Initially, when I first saw this I thought there was no way there could be an opening in this. But after playing with the blister like bubble and squeezing it (I thought it might be a zit at first) it appears the fluid that's filling the blister-like bubble is pushed down the vein-like track towards the penis head and exits the 2nd hole/opening which a clear sticky fluid clearly exits. This hole is about a 1/2" below the penis head. Upon squeezing the blister-like bubble which always appears about 1/2 way up the penis shaft the bubble subsides for a little while but appears again as is it's full of fluid again. I'm very nervous/worried about this. Please help!
