Does sucking nipples can infected by STD's types?

Hrmm I heard from somewhere that sucking a nipple would cause other types of STD's though

Isn't that part of oral too?

Doesn't saliva count as bodily fluid?

What if the nipple lactates? does that count as bodily fluid?

Well in that case is Herpes, Syphilis, Chlamydia and Gonorrhea curable?

I know HIV isn't

Well knowing the curable state of gonorrhea, syphilis and chlamydia what are the early signs for those?

Well you just mentioned that all the mentioned above is if you had unsafe sex. But these symptoms includes if you perform oral as well right? just like nipple sucking.

Well with your statement even with a condom we still can't prevent cases such as through french kissing or nipple sucking right?
