First and most important, I will confirm what I think you already understand -- that this was a zero risk event in regard to any and all STDs. No STDs are transmitted by hand-genital contact, including gonorrhea and regardless of whether saliva or even genital fluids are used for lubrication. The biological reasons haven't been studied:  if there are no such cases, there is obviously no incentive to do research on the details.

That said, you raise an appropriate issue about gonorrhea and saliva. Transmission of gonorrhea by kissing probably is real but has been documented only in men having sex with other men, in whom kissing may be more prolonged or otherwise somehow more risky. And urethral gonorrhea also can be acquired by oral sex. However, the mechanism isn't necessarily via saliva, but perhaps with contact of the meatus (urethral opening) with the back of the throat, which is the infected anatomic site for oral gonorrhea. To the extent there might be a small STD risk from hand-genital contact, it probably is limited to those infections transmitted primarily by skin-to-skin contact (HPV, herpes, syphilis), not those transmitted primarily by infected fluids (gonorrhea, chlamydia, HIV). In my 50+ years in the STD business, I have never encountered a patient with gonorrhea or even the skin-skin STDs whose only plausible exposure was hand-genital contact.

I'll also point out that absence of symptoms (urethral pus, painful urination) within 5 days is nearly 100% proof against you having gonorrhea. Asymptomatic urethral gonorrhea can occur but is quite rare.

In summary, I would advise against STD testing on account of your recent CSW experience; and it would be safe for you to continue sex with your regular partner, if you have one.

I hope these comments are helpful. Let me know if anything isn't clear.

The risk is virtually zero even if i am uncircimsized

The to an extent factor(skin to skin) you explain is more a theoretical thing that might not happen at all in reality 

I can put this incident me behind me and move on with my life without any and all testing unnecessary for this specific incident.

Thanks again, this service is highly appreciated.

Ps. After your last reply I will also take up on your other advice to stay of the internet regarding the subject

See my "In summary" statement above -- which indeed is consistent with "I can put this incident behind me...without any and all testing...." I also agree with avoiding the internet rabbit hole! If you feel compelled to keep at it, do your best to limit searching to academic, public health, and professinally moderated websites and especially avoid those by and for people with STDs or at risk (like Reddit, for example).
