im 21 years old all the sudden my penis seems to be more sensitive like within the last 3 weeks or so when i masturbate or even when i have sex but more noticeably in masturbation i ejaculate within a min or 2 and i dont even need any stimulation like i dont have to be watching porn or anything before i would last longer pretty much as long as i wanted to and to get off i would have to be watching some sort of porn also i noticed this light blue vein on the left of my penis that is more clear now that i didnt notice before and another thing when im erect i stay erect longer now sometimes even after i ejaculate i stay semi erect for a good amount of time after i dont have any pain or anything just dont know why all the sudden its so sensitive and doesnt take long for me to get off
