It seems like something with your immune systems that makes you receptive to gonorrhea so easily. Kissing is not a zero risk but considered relatively low risk provided you have been fully vaccinated for HPV, Hepatitis A, B, C and other preventable STDs. The other likely STD you can catch from kissing and oral is Chlamydia, which is incredibly popular STDs these days, fortunately it is quite easy to be treated with just 1 dose of antibiotics, but you should screen for it as quickly as possible. There is risk in any activities in life, even the most benign activities such as cuddling can expose you to some risk (monkey pox etc). If one is to be totally safe, then sex and pleasure is nonexistence and what is the purpose of life then? The best weapon you have against all these nasty things is your updated knowledge on medical sciences and treatment, take the calculated risk and know that you can recover if you are unlucky to get hit with one, just always be alert and get tested regularly, take any preventive measures such as being vaccinated if possible.
