Ah..there it is. Your growth out is about to come very soon. Warm and hot penile shaft hours later is a major indicator your cellular activities are going wild. Congrats brother. Keep it up.Indeed there is a slight feeling of warmth, accompanied with a mid flaccid size.
I can say that since i've been going easy and not forcing the exercises like a maniac i started feeling this.
Aslo the erection is much stonger, probably from the psychological effect of growing.
I will be reporting the unusual feelings and changes from now on.
