Do I have a yeast infection, I don't have burning , itching , or an odor but when I have sex and he pulls out there is white stuff on his penis, it's not like a lot but it's embarrassing, is it a yeast infection ?? What do I do if it is ?? And I know it's not cum! And I'm 17 and if I ask to go the GYN my mother will flip shit, so I would like to try to avoid that.
