There is no risk from this.
I understand that you are very knowledgeable when it comes to HIV/AIDS, and I do believe you, but can you tell me why this is a no risk situation?
By the way, I have anxiety issues, especially about diseases, so if this sounds redundant, its the anxiety typing.
And by "very deep" I mean deep enough to require medical attention and stitches.
So it doesn't matter that it was more like a bruise than a scab that broke open?
Doesn't matter at all. No risk
Thank you very much, if it means anything, you have greatly reduced my anxiety, and it is hard to do that.
