<human>: Can you succinctly summarize the text in 1-3 sentences?

So I feel like this takes a little (awkward) explaining. I had no particular skin irritation at the time, but I suppose my skin can be a little sensitive. In an extensive kissing session two days ago, I think my dude's very small amount of stubble kept rubbing against my chin, and over time it just wore away the skin.  
It happened the last time, too, but not as bad (but we'd kissed for a shorter amount of time then, too).   
It looks like a very minor burn, almost; the scab that has formed is more of a light brown or yellowish colour, no red in it, etc. It doesn't hurt or anything, it's just awkward because I have this scab on my chin from making out, you know?  
I don't know that any further information is relevant but I am 23, white, female; past that, the other questions really don't seem important.
<bot>: how do I heal this raw-skin-induced scab quickly? And is there a way besides avoiding the cause to prevent it from happening again?
