Lulump\bumb penis shaft, don't think its std.I need ad-vice!
It all started about 1 year ago around new years eve. I masturbated 3 or 4 times in a row that night and I had like erosion on my penis the next day, I didn't make a big deal out of it knowing it was due to too much masturbation. It left a couple weeks after. Fastforward to 3 weeks ago about, it reapered on my shaft again, it's a hard lump and when I sqeeze it sometimes pus comes out, then it decreases in size, but it takes so long to go away that I'm worried about it. It doesn't hurt at all, and I don't think its stds cause I haven't had sex in a while and it first appeared after an intense session of masturbation, now its been at least 3 weeks, and it did decrease in size, but its still hard and pus still comes out of it at times.
Could anyone help me out here, I think it may be a abscess or is it? I need help with this, anyone have had a similar problem please help.
Thank you
p.s this is pretty embarrassing but I want to know what this is. Thanks
Pps. I'm 21 years old if this helps at all.
