Hi, I Was Just Wondering If You Could Help Me,

Hi, I was just wondering if you could help me, I was receiving a hand job a few days back and she got quite vigorous so what I think was a think layer of dry skin pealed off the belend but without me realising that I inserted the penis in her vagina not fully just the tip and pulled out.
She's hiv negative so I was wondering if I could contract hiv?
