When i masterbate i don't really feel much in my penis. but i get a really werid feeling in my prostate and then ejaculate. how do i stop this?

Normal: No two men are wired in exactly the same way. A majority of men get a squeezy feeling in the lower abdomen for several seconds before we ejaculate. Most of us find this pleasant and hopefully you will as well. It's good that you're able to ejaculate and are learning about your body in preparation for what may lie ahead as husband / father. Key will be in relationships themselves.
