Whenever I penetrate I ejaculate even I can't do one sit up. I think my penis head is very sensitive.
Earlier I used to masturbate in very strange way, I used to lay on the bed by stomach side and rub the penis in bed so I ejaculate before my penis fully erected. Should this can be a reason for all this is now happening to me. I am feeling very embarrassing. Please help me to tackle this
