I'm trying to learn to harness my sexual energy instead of ejaculating it all out. I just started doing the breathing and kegel exercises about 4 days ago, and The first 2 days I succeeded in getting really close to ejaculation but holding it off with my pc muscles . The third day I failed and ejaculated. Today I tried again but I went passed the point of no return again, but this time I used the finger lock method to stop the semen from coming out . It worked, but it's like right after I did it my testicles and my urinary tract felt kinda achy almost like I contracted them too hard or something. I did not pee the semen out so I don't think it went into my bladder. Is this normal for my first time? I am only 17 . If anyone here can help me I would really appreciate it!
