Haha that's the curse of kegels. Instant erections. It's not harmful and you shouldn't stop. It's all mind control. I had the same effect when I used my PF but now it's all good. No erection. Unless I'm thinking dirty then I have to wait around lol. If your doing a routine and get hard, do erect stretches, that will still give length gains but help make the erection subside. That's the hardest part of PE for me. Trying to keep these hard ons in control. Masturbation helps but don't become dependent on it. Relax first, then think of something that upsets you and do a reverse kegel while squeezing your head and let the blood out. That works for me.Just relax your mind and body. It's self control above all else. Sucks but you can learn. Don't get upset. Use it to your advantage whenever you can.
