Hi this is an embarassing question but I need to find out. I am 21 with cf, and until recently had not had sex for about a year. Back then I never had a problem, but with my current girlfriend, I get aroused but not enough to have sex. I have read that cf is not related to this but that diabetes(which i also have) may be a cause. I am comfortable with my cf doctor and want to talk to him about this, but would he be able to prescribe me some kind of medicine for this since I am not comfortable talk to my diabetic doctor about it? Thanks
