Red spot on penile glans, one week later (pics). Is this shaffing or something else?

Today marks a week since I first noticed what seemed to be a red spot on my penile glans on the corona.  I had first noticed right after masturbating in the shower (based on experience, water and friction don’t mix well) , and this was the day after I partook in some sexual foreplay that involved a lot of rubbing, receiving oral sex and masturbation. Mind you, I had also been masturbating quite often lately, even two days after noticing the spot. Yesterday I noticed what seems to be some changes. Let me just say that I am uncircumcised, but I try to keep my foreskin retracted just because I am capable and I feel like it stays cleaner that way. Last night upon observing it before bed and taking a pic, it seemed to be drying up. This made me think that maybe it was just shaffing from all the masturbation and possibly hurting it during sexual foreplay (maybe teeth, tugging, etc) and it made me feel like it was healing. This morning after showering it seemed to be a bit more red. Mind you, my foreskin tends to tract back into place overnight so I’m sure there was moisture from that as well. Anyway, I decided to take some more pics this morning, and what I noticed is that it looked more raw. I had been worried that this was possibly a wart at first, but now I really don’t know. First pic is from last night when I noticed it looking dry, and the second pics are from this morning right after my shower. What do you think? I still do not have peace of mind about this and just want it to heal already if it is nothing serious, but it’s been a week. What is taking so long? 

Hey everyone, any opinion on this? Have received a reply on this post and I am still anxious about this. Today is now day 8 and it worries me to still see this mark. Can it be that it’s just not healing faster because I am uncircumcised? Or is it something else I should be worried about? Someone help please.

Anyone have any opinion sort of opinion on this? I am EXTREMELY anxious here. Wish someone would answer :\
