Note, I have the plastic tip of the syringe pressing into my flesh with the 5/16 needles. I don't think the 5/16 needles will work for the auto injectors though.
A. Both. I have concluded that if I inject in a more flaccid state (rare) I use a 5/16" because my flaccid unit is a bit over 1" dia. However and usually we practice extensive foreplay and roleplay in advance and I can have a well engorged unit that is closer to 2"+ and I normally use a 1/2" needle. Having it engorged also provides a better visual target to avoid exterior veins and prevents the skin from sliding around so you can get a 3 or 9 o'clock point better.
