If your girlfriend has a cold or the flu, can you catch it from her just by having sex?

I know that a cold or flu can be transferred from any exchange of saliva, but can it be also transferred by having unprotected sex.? If you do have to wait, how many days should you wait for intercourse after the first symptoms?If your girlfriend has a cold or the flu, can you catch it from her just by having sex?
The very air she expels, has the cold virus in it, as well as her hands and any other part of her body that she touched ... after stifling a cough or sneeze. The only way to avoid catching her cold is to stay away from her, for the duration of her cold. Sorry, no nookie for you! :(
it is not sexually transmitted but if you are that close you are bound to catch it anyway. I doubt she would be in the mood anyhow if she is sick
You can catch it from just being in the same room.
damn dude you don't have enough respect for your girl to let her get well.
well. i think your partner would be too tired to do it. it's not a good idea. when you're sick, level of activity decreases. Wait until she feels better.
