I am 19 and have been sexually active since I was 14. For the last few years I’ve been very sexually active. For the last couple months I’ve noticed that when I get erect whether I am masturbating or having sex with my girlfriend I develop a bump on the right side of my penis. It’s on the underside near the tip. It’s about an inch long and it’s hard. Like I said I never noticed it when I’m flaccid or if I just get erect for a short period of time. It’s only if I am erect for long periods of time and the activity is more strenuous than normal. I’ve also noticed that the bump is right where either my fingers or her fingers are when my penis is being masturbated. It doesn’t hurt I’m just curious what it might be. I’ve included pictures.
You can see in the second picture that the bump is less prominent while I’m flaccid . Also how would you bring this up with the doctor?
I’m not fully erect in that picture so it’s not as clearly visible as it usually is.
Hi andrew,
It’s likely that you’re describing a penile lymphocele (aka lymphangitis obliterans). The cord-like swelling you’re feeling is a swollen lymphatic vessel- when you develop an erection, blood and lymph flowing through the penis is temporarily restricted. That’s how your penis stiffens and enlarges. Unfortunately, prolonged and frequent erections can impair the flow of lymphatic fluid, which is why these vessels start to swell. It’s not a serious condition and medical treatment unnecessary.
Most cases resolve after a break from sex and masturbation, so try to hold off for maybe 2-3 weeks and allow it to settle.
Rgds,
