Gosh, I diagnosed 27 years and on 2nd hubby.. Got both whilst diabetic, went through boyfriends n partners inbetween no1 and no2. Never honestly gave it a thought that any of them thought any differently of me because of my D. Never came up as problem to any of them..
So in answer.. Nope, no problems dating with type 1 at all.
Mind you, I've always ate and drank the same as anyone else... I always injected in front of everybody, never hidden my diabetes, or made myself any different to non diabetics...
Nowadays with a pump, i wear it on my arm, and my cgm on the other arm. Only ever had one person comment.. Told them it was new versions of probation tagging!!
