Abrasion on penis?

Hello, I am a first time poster and am quite concerned about the abrasion on my penis. It happend by using "lube" when masturbating but it was obviously just some cheap lotion so it didnt work very well. I was doing it quite often until i could feel the skin start to kinda burn off so I stopped doing it. I looked down and there was alot of skin removed, there was NO redness no blood or anything like that. It was simply the skin being removed. I never really let it heal, but I did notice it start healing in the week that I didnt self-pleasure. I tried to heal it again, this week actually, I havent beat the meat since monday and I am noticing no noticible change or skin coming out. Did I damage my penis forever? and, I use vaseline, and occasionally some moisturizers, but I dont really notice anything. Is this something thats gonna take a long time to heal? Am i prone to std/sti's? Honestly, I am also a "self sucker" so I did a bit of that while the abrasian still existed...

Any tips? aside for lay off the wacking (which I am) , am I prone to std/sti's? , Is it safe to have sex with this abrasion (unprotected)?

thanks
