I have been jelqing for a couple of months and haven't noticed anything. But I was wondering, can jelqing decrease sensitivity of the shaft? It would make sense seeing how you put constant pressure on the shaft for a certain period of time (15 min in my case). Basically will it affect the sensitivity of the penis during sex? Hopefully I'm wrong and it doesn't. Is there anyone who has been jelqing for an extended period of time who can say if it has had an effect or not on the sensitivity of the penis, especially during sex. Thanks
