First, what is a yeast infection?
my girl said she has one and isn't supposed to screw for a week or two because of it. I've already nailed her twice since.
is it bad to screw during one....I know nothing about this. could someone give me some info?

oi'm pretty sure that she could give it to you,
and it will burrrrnn

google.com, genius.

It is characterized by Itching and burning in the vagina and around the vulva (the skin that surrounds your vagina), A white vaginal discharge that may look like COTTAGE CHEESE, pain during sexual intercourse , swelling of the vulva-- for the female.
It can be trasmitted through sex-- penile yeast infections DO exist--so if you're willing to risk all that, go ahead and bang away.

And for clarity, here is a link: http://www.herpes-coldsores.com/std/yeast_infection_pictures.htm

::edit::
The point is DON'T until it's gone.

Don't have sex anymore until she is 100% positive that it's gone.

A white vaginal discharge that may look like COTTAGE CHEESE

sounds more like frottage cheese

but seriously that sounds similar to smegma

ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

fuck...wish I had thought this one through a little better before banging her out....at least one time I had a condom on. and the other time she had blown me for like 20 minutes before, so i came real quick.....

is this like an STD or something, or just an infection?

totse pictures dont usually disturb me but that guys dick looked like a jigsaw puzzle with missing pieces
