Hey Buckfever,
Stretching also reduces my EQ. Sometimes drastically. For some people it may be different, especially if the stretching is done lightly. However don’t forget that most people, when starting something new and health related (PE) don’t stop with the physical aspects. In general they start looking at their diet and exercise a bit more, maybe stop smoking, drink a little less, supplements etc. Also being optimistic about being able to get an actual, real life bigger dick can be a huge boost to confidence and/or EQ. On top of that you probably don’t only stretch, but jelq/pump/squeeze/edge also.
That said, maybe (light or otherwise) stretching improves your EQ! Good PI for you then, keep stretching. For me clamping and edging are EQ champions and stretching is somewhat of a killer. Except for JAI stretches. But don’t forget the surrounding factors too.
Good luck!
