@tinci01:
I can't belive I'm writing this specially when I don't have prostate, but my dad does and he made me google it because he had problems with it.
This is from what I learned on google and from straight porn.
You should massage prostate after you're already arroused or it will hurt (probably).
you'll know that that's prostate because it will enlarge and you'll feel your heartbeat when you touch it. Here is a little help http://makeupinindia.in/mag/secret/scientists-expose-mans-g-spot/ You do shake when you orgasm. You also might feel like you need to pee because that pee tract or whatever is called that comes from bladder goes right pass your prostate. You should have prostate massage once a week. If you do many times more can start hurt. Also if you do it for longer time, I think it start hurting. But if you do it right like you did last time, well you know how it feels.
And if you don't do it, sperm starts to stay in prostate and that can grow into cancer, That's why my dad says that it's not that common for you guys to have prostate cancer as it is for straight guys, because when your partner hits your prostate also empties it. Belive me, alternative to empty prostate isn't that pleasant. Doctor takes some sort of very narrow stick that has something that looks like crocodile teeth at the end and scrapes what's inside your your prostate through pee hole. How nice, isn't it.
You also can get pain in your penis if you don't empty prostate and then it can shrink or it gates painfull shape.
Also if all of the sudden your penis starts to shrink, then something is seriously wrong with you. My dad went to therapy for some other reason once and they were "curing" him with magnets. His penis started to shrink, so he stopped doing that. His uncle knew how to cure cancer while he was alive and he told him about penis shrinking. So if that happens to you, just think what you did right before that happened and stop doing it.
And if you get problems with prostate, this plant is the best medicine. It's beed tested https://en.wikipedia.org/wiki/Epilobium_parviflorum In Hungary they sell tea out of it. looks like this https://bevasarlas.tesco.hu/groceries/en-GB/products/2004120082895
Ok that's all I know, I think. I hope it helps someone in the future in case you guys don't know that already.
I am a Biochemist and teach a class on cancer. Sperm can not turn into cancer. Generally cancers uncontrolled division of abnormal cells in a part of the body. It can be multifactorial, meaning genetics and environmental factors come in to play.
