What would cause my penis head to become dry and cracked?

[archen]

My penis head suddenly begin to look dry and cracked a week or 2 ago, like a raisin. I'm unsure as to why. At least, I don't remember it looking like that. Maybe my worry is making me look at my penis more closely than before.

I had protected oral sex about a month and a half ago, and I should get an STD test this week. This is the only sexual activity I have ever had.

However, my issues weren't really symptomatic of any STDs I found online, and I don't think it's that likely for me to have gotten an STD from protected oral sex.

Here are some pictures for reference.

Also, I masturbate a lot. Not sure if that could have caused the issue.

I appreciate any help anyone can provide. Thank you!

Your penis looks like a raisin? Your worry is that having protected oral sex could result in an std that is causing this?  Worry no  more about that.  You used protection which is great.  That is going to prevent transmittance of an std through the oral you received.  Personally I don't even think you need to get tested for that.

Your symptoms sound topical.  Did you change soaps?  Wash really forcefully with soap?   If you don't use lube to masturbate, that could also do this.  What about chafing? If you run and sweat a bit, and keep running and the pants are rubbing just so, the chafe can happen. (just one kind of scenario that can result in it).  You could always get it looked at.  Yeast could cause it but from protected oral sex, I'd not really think this would be the case.  I'd use only a mild soap and be gentle and careful if you masturbate (maybe give it a rest until it's better).
