1. Can I get any other stds from this contact? HPV, Herpes, etc? Can I get anything at all from this?
2. Should I test for Herpes? What kind of test?
4. Was testing at 9 days pointless?
5. What’s the best type of testing for Trich and HIV
6. Should I retest at a later date?
7. Are the swollen lymph nodes connected to this? HIV, Herpes?
You had no risk for any STD from this encounter. I'll include links at the end to help explain why.
3. What is causing my penis tip redness and irritation? It wasn’t like that directly afterwards and took a couple days to develop. Can anxiety cause redness and irritation? Can std symptoms develop that quickly, 2-4 days?
The oil might have caused irritation, or it's anxiety that is causing you to check a lot, causing more irritation.
STD symptoms can develop at 2-4 days, with 2 days being the earliest, but you had no risk. You've also tested negative for white and red blood cells, indicating there is no infection.
Are you anxious because you went outside of a relationship? Another reason? Remember that guilt does not equal risk.
