Upward curve.

I have an upward curve too. I put a —————lot—————— of extra lube on the glans. For me, that has ensured that it doesn’t get stuck or smushed against the inside of the cylinder.

I have only been pumping since February. However I have noticed during the last few sessions that my unit seems to now be straightening out in the tube, so that the glans is no longer in danger of sticking.
