In your first paragraph, you say, "now painful urination, no discharge, no sores."
Did you mean no painful urination? Am I correct in assuming you have no symptoms other than the random tingling you mention?
Both of your partners sound pretty low risk. Oral sex is lower risk than intercourse.
For receiving oral, you could be at risk for gonorrhea, chlamydia, syphilis (uncommon in most developed countries), genital herpes type 1 (the type that causes cold sores, and can be transmitted to the genitals), and NGU (a bacterial infection in the urethra).
If you already have oral hsv1, you don't need to worry about genital hsv1. Even if you've never had a cold sore, you could still have it. 90% of the 2/3 of adults that have it globally never get symptoms.
NGU can be caused by things like bacteria that resides in the mouth normally, strep bacteria, viruses that normally cause upper respiratory infections entering the urethra, etc.
Getting gonorrhea and chlamydia from oral is much less likely than if you had unprotected sex.
From giving oral sex to someone with a penis, you can get oral gonorrhea and chlamydia, and syphilis. The chances are lower here, too.
You can test for chlamydia and gonorrhea at 5 days post exposure, and make sure to ask for an oral swab test, too. You can test for syphilis at 6 weeks, though if you're in the US, Canada, UK, etc., I wouldn't overly worry about that. You can also get an IgG type specific herpes test now, and again at 12 weeks if your hsv1 test is negative, but I'd caution against that. The hsv1 test misses 30% of infections, and it's done at the same time as the hsv2 test, which has a fair amount of false positives. Unraveling that can take weeks and several hundred dollars. I'd imagine that would be stressful, not to mention hard to explain to your wife.
If you get sores on your penis, you can get them swabbed.
Most experts don't think oral sex is risky enough to even warrant testing after 1 exposure. Since you have tingling, you might test, especially because you're married, but I agree - that could be anxiety.
