I sometimes get hard while stretching and I’ve been doing it for 5 months. Do you sit down or stand up while stretching? I sit down when I masturbate and sometimes sitting down and touching my penis will get me hard. What I do is stand up, spread my legs apart like I’m a catcher in baseball just about to squat. Then, I close my eyes, and I concentrate on every single breath I take. I only concentrate on the sweet, sweet oxygen entering my mouth, going into my lungs, and the reverse process while leaving. I do my breathing very, very slowly. Concentrate very, very hard on every single slow, slow breath. This is my technique, hopefully someone else has good ideas.
