Hello. I hope this question is appropriate for this section.

This is something that has happened a few times. When I urinate, sometimes it looks like light soap suds. And I'm not simply referring to it foaming up in the bowl. I mean that I literally touched it as it was coming out, rubbed it on my fingers, and it looked kind of like soap. I usually notice it happening when I'm almost done urinating, and it doesn't seem to happen all the time.

I think it would be good for me to tell about the first time I noticed this, as that was the most noticeable time it ever happened. One morning, a few months ago, I had just gotten out of the shower. I then went and urinated. After that happened, small drops of urine were still dropping (which I suppose is normal). After that I went to continued urinating and kind of started forcing it. I started to notice little white bubbly spots at the top of my penis, and soon after that, I noticed what looked like soap underneath my penis. It looked enough like soap, to the point where I actually wondered if I merely didn't rinse thoroughly down there in the shower after washing myself, but I figured it was connected to the small bubbly spots I noticed earlier. I would appreciate any information and help on this, because it's on my mind a lot lately.

Can someone tell me why this is, and if it's normal? Also, if this is normal (like, if it's normal for urinate to look sort of bubbly when you touch it and rub it on your finger), please tell me. I did some research about something in the penis called smegma. Is it possible that's what this is?
