Can I get an std if I was fingering a girl and scratched a small mark on my chest cause it almost immediately caused a rash?

Asked by Enquire101 on December 9, 2019

Was fingering a girl while she performed oral and scratched my chest only for a rash to form. In the last few days the rash has been getting worse. Would like to know if this can spread an std or of any indication that I have one? Thank you in advance!
