Penis Pump newbie routine

Hi all,I’m new to this penis enlargement routine so bare with me. I started the newbie routine and I can see the veins in my penis getting significantly thicker, and I get erections easily. Is this a good sign? And I recently purchased a bath mate pump, but the problem is I can’t keep a full on erection when my penis is inside the pump, is there any solution?
My current routine is:
5 minutes warm up
15minutes pump
10 minutes stretch
10 minutes jelp
25 kegel exercise

Cheers!
