I was diagnosed with type1 when I was 11 months old, so for me, it's just "oh, yeah, I like to do this and that and oh yeah I've got diabetes blah blah" Most people nowadays know someone with it, so they'll probably have a slight grasp on the concept. just tell them (I say it in a way that comes across as funny) that all they really need to remember is if you pass out, call 911, and make sure they know about the diabetes. If things pan out, you can tell her more about your glucagon kit, etc. As for the other inability, I'd say it was 99% mental. First time with the new girl, wondering if you'll be able to maintain an erection... it happens, man. Personally, it's only happened to me a few times, but I just take a correction bolus and as soon as it hits I'm good to go. Worse comes to worst, just eat some cinnamon. I don't know why, but it makes the high blood sugar symptoms go away almost immediately- and drastically- don't take too much or you'll feel low. That, along with taking your correction bolus and taking your time with foreplay, will buy you the time you need.
