Just keep going anyway. Sometimes i don’t even get erect to jelq and as I’m doing it it will start to get semi erect and I keep going. And then maybe later on it gets more limp. I think that’s the best of both worlds cause you have varying erection levels and hit every end of the spectrum. I guess I have a weird method because my dick is almost bent at the end. It’s not that it has a downward bend so much, but the head kinda just curves down. I hate it.
Anyway, as I’m doing jelqs I kinda bend it up at the end and if it goes soft I’m almost combining stetches, jelqs, and even bends all in one. I find my 10% jelqs to be better than erect ones cause you get a stretch kind of and a jelq in one. Good luck.
