I am a 16 year old, circumcised male. For as long I can remember, masturbating has never felt that good. I have developed a unique technique that feels pretty good, but it never feels good when I use the conventional style. I can ejaculate, and the climax/ejaculation always feel good, just the actual process never does. I am a bit concerned, but not too much since I can get an erection, and the ejaculation feels good. Ive never used any lubrication. could this be the problem? Any tips, opinions?
