Hey all. I'm just starting PE and I find it almost impossible not to get a full erection while jelqing. I've tried just waiting it out, but my penis is just way too sensitive. If I am doing a simple 10 minute routine of jelqing, and just wait for my erection to go away everytime I get one, the 10 minute routine turns into more like a 40 minute routine. Now, I've heard this isn't recommended, but the only thing that has worked for me is masturbating before my PE routine. If anyone has had success doing this or no success doing this, I'd like to know. Also, I would like to know the scientific reason that masturbating before or after PE is supposedly bad (I masturbate before only until the next session). Thanks.
