I've been searching online but can't seem to
find the specific information I'm looking for, and I
don't know if anyone here would know... can stomach
viruses be transmitted through saliva/kissing?

I'm a major emetophobe and I recently found out that my
boyfriend's roomate has some kind of stomach bug...
typically my method of reasoning for seeing him would
be: however long his roomate is sick + 3 days he could
be contagious afterward + 3 day incubation period in
case he is sick... so I'd wait about week to see him
after his roomate is "better". But we haven't seen each
other in a while and he's pretty upset that I don't want
to just because he was exposed to something, so I'm
trying to convince myself it's okay and I won't get
sick. (which I'm sure you all know is practically
impossible!)

I've read on some sites that as long as you don't have
any symptoms, you're not contagious. Others say you are.
Then I found this one website:
http://www.emetophobiahelp.blogspot.com/ that says
kissing someone who shows no symptoms can't infect
you... but it's not any kind of official medical website
and I couldn't find the same information anywhere else.

Can anyone confirm this? It'd be nice to know that as
long as he's all showered and clean and washes his hands
and isn't showing any symptoms, it's unlikely I'll catch
anything...

He doesn't worry like me at all so I'm sure he probably
hasn't been careful about washing his hands and whatnot,
which scares me. The last time someone was sick in my
house I was washing my hands probably 5-10 times an
hour, wiping off faucets, door handles, etc. with
bleach, and I starved myself for days after she was
better. (and I avoided it!)</font>
