I tried it a while ago, I got nowhere with it.
I'm coming into this almost 1 1/2 half years later, but I'm a type 1. There is no way I can really keep my diabetes a secret with all the testing, insulin doses and just the risk that I might go low. I've never had a guy get scared off by it though.
That just seems really odd to me. Maybe it's demographics. I tend to live in big cities where folks are around a wealth of different people including those who have medical conditions whether they're chronic, like diabetes, or terminal, like AIDS. People go with the flow. I think disclosure is better than not. Plus, it can be grossly misinterpreted if I don't disclose it. I wear a pump now, but that's been mistaken for a beeper but I also still carry syringes. Those without context can look sort of bad.
It's better to keep comments like this to yourself.
