For HIV the chance is small for vaginal intercourse. If she was positive 0,05 to 0,1% per act, still for reassurance you can do a rapid 4gen test 6 to 8 weeks post expoture to get peace of mind. The cancer sore, how long after your exposur? How long do yiu have it and how does it look?(size, border and if it's open or not) this because if given oral to her there is a small chance on syphilis(very small chance as it normally is rare in hetero's)
Hello,
Unprotected penetration poses a risk of HIV transmission.
An HIV test at the right time will give you accurate results.
A 4th generation test should be done at 4 weeks post exposure and a simple HIV test at three months post exposure.
Keep calm and test at the right time.
Take care
