After a few hours of browsing, I got the impression that most sex are relatively safe, except for unprotected anal/
vagina sex. However, I still have some doubts
on some other forms of sex. I always take precaution on my part but there are some other possible risk which I thought is still exposed to me, all figures are approximated for easier deduction. I shall elaborate them neatly and hope experts can help answering.
