Here goes nothing,
basically for about 4 or 5 days now I have had what can only be described as a bump on the botton left side of my penis, when my penis isn't erect it looks quite big, but when it is erect its still pretty big, when I feel around the area underneath the skin it feels as if there is very "fat" vein underneither, I have followed this vein up and down my penis with my fingers and it seems to get thinner and more "normal" as I head up to the head of my penis, but when I get to pubic area it gets very sore and tender, also, when I pull on my penis or jerk it to the right it it very painful indeed.
This is the first post of these kinda things iv ever done so im a bit nervouse of how this will get portrayed, but I just wanna know if I sohlud be worried, or anything like that as iv never had sex before but my girlfriend and I wanna try it, but everytime my girlfirend "hints" that she wants to do it I kinda push her away because I am afraid of what she will think.
Please help me!
