White growth on penis line

I'm a 30 year old guy and sexually active with my wife. This white growth has appeared on the bottom of my penis like on the line, almost feels under. Its hard and a bit sore when I touch or squeeze it. Any idea what it is?

can anyone help?

When did the growth first appear … ?

a week ago. It appears to be hard and not something I can remove. not really painful unless I squeeze. unsure what it is.

I found out after telling my partner that she’s been itchy the week prior and had vaginal pains and didn’t tell me…

This is certainly an unusual, and therefore an unexplained growth. If you monitor the development of this, if it does not begin to fade in the next 2 to 3 weeks I would get it checked by a medical professional, you may need to see a Dermatologist to confirm what it is.
There is a strong chance that it is not linked to your partner at all.
