Hi! I just read that thread however I cant seem to see where they say what exactly qualifies as fluid sharing?

A while ago I asked something about how manual sex, and the mechanics behind it, does not pose a pregnancy risk. Heather told me that it is not possible because there is not direct genital to genital contact and there is no exchange of fluids going on. My question is, what exactly qualifies as an ex...

Yes, I think Stephanie got the gist of my query!

So there is really only a risk with semen, because with the pre-ejaculate the conditions are not possible?

Is it not fluid exchange if pre-ejaculate and vaginal fluids meet, whether or not it is through genitals or fingers? From what I see, based on your statement, pre-ejaculate from fingers to the vagina does not count as fluid exchange and in the process does not give the conditions needed for pregnanc...

What exactly are the mechanics behind manual sex that enables it to be a no risk sexual activity? I just can't seem to wrap my head around the factors at play, considering the fact that bodily fluids are also taken into account. I would really appreciate it if you guys were to give me an answer to m...
