I understand.
Make sure your inviroment is really warm. I like to keep my temperature around me in the room at 30°C/86°F in order to promote maximum blodflow. If I do not do this, my penis can get cold if I do pumping and
SSJ's for to long.
I even kept my heating fan on when I already had 30°C in my room in the summer. My belief is that 35-40°C (95-104°F) would be the optimal temperature to do PE in, but I cant get it that high. A big sauna would be the dream inviroment for PE.
I also look at pornographic to boost myself, even if this is not optimal or even good for myself. I do it. With no woman around it's my only choice.
Maybe some tips there.
