Dark Spots on Shaft of Penis

Men's health
1

So I was in the shower today, and I figured hey I’ll do a testicle exam, feel for lumps what not. Well nothing alarming, but as I was looking at them I noticed the pigment all on the shaft one my penis looked kind of spotty on the right side and it appears like there's quite a number of these spots some larger (1mm), most are smaller. 

Whatever these are, aren’t raised but look a little edged, and look brown, some spots darker (keep in mind I’m fairly dark skinned in that region anyhow). They seem to be more present where there are veins. 

I’m a healthy 35 year. Don’t smoke don’t drink, eat pretty clean. I’m not currently sexually active, I haven’t been for awhile. I have been a bit stressed lately though too. 

Just wondering if anyone has any idea what this could be? I googled and it said it could be lentigines, melanotic macules or some sort of melanosis.  So I’m not jumping to conclusions here, and my doc is off for a month. 

Thank you.

These marks don't look like anything sinister to me.

I think if you examined other areas of your body closely you will find similar AND different marking to the skin surface exist across the body.

Obviously, we should all be cautious we we find things that may be of concern - I would suggest monitoring to see if it worsens, and, by all-means, mention it to the next medical professional you see.
