Chances of you getting herpes from a 1 time, protected encounter are about 1 in 10,000, so quite low. I can't tell you what this spot is you have. You should let a doctor see it, though, since you did have sex, and you are married. It could be irritation, chafing, a fungal infection, or a host of other things.
It's not syphilis, though, since that wouldn't appear this soon - that takes at least 3 weeks to develop.
1. If I was to have an outbreak i need to wait around another week?
Herpes sores typically show up within 2-12 days. Since you had a protected encounter, I'd be very surprised if you got it.
2. If I don’t develop this classic pictures should I test ?
No, I wouldn't. There are a lot of false positives on the IgG test, and unraveling that can take months and a lot of money. If you don't live in the US, it can be impossible.
3. What would be my chances of one protected encounter?
About 1 in 10,000.
4. It’s anxiety or guilt because I am married , either way I have postponed sex until further notice.
Anxiety wouldn't give you a red spot, but lots of other things could. Herpes probably wouldn't, but a simple fungal infection might, or irritation, folliculitis, etc. Let your doctor see it to be sure. If they think it's herpes - even possibly - make them do a type specific culture on it. Don't let them just give you a visual diagnosis. It's often incorrect.
