well im a lad of 18 and i have not had any Sexual experience what so ever.

Everytime i "Jack Off" i dont seem to ejaculate properly.
i get that orgasm feeling but nothing come outs.
i am really worried and i have seen my local doctor numerous times
he just says "look on the bright side, you wont have kids!"

i have ejaculated blood at times wich i dont think is correct.

i also have these very weird looking pimple things on my scrotum,
they look like acne but when i popped one, the "puss" was black and a little red.

i jack off to hentai if that helps.

i told my dad but he just says, "im not your real dad so *** off"

Please help!
