Red, painfull swollen foreskin

my forskin is red and swollen and hurts when you touch it. Im 16 and still a virgin so it cant be an STD but yestoday i was masturbating and a white buildup was in my seimen befor i ejaculated
also i had cleaned underneath my forskin yestoday in the shower and today later in the day i found it red swollen and pain full to the touch...what could it be and what do i do?????

i had a similiar situation to that when i was younger n still a virgin.. jus keep cleaning it thoroughly everyday (day and night would help).. plus go see a doctor.. he'll probably give u a simple cream to apply once a day.. its most likely nothing serious just a small infection

I am 18 virgin and i can retract my foreskin no problem both flaccid and erect! i am able to do so from stretching day by day, wank by wank, etc. . .
BUT, when i leave it retratcted for a long period of time, the ridge of foreskin behind the head starts to swell and sorta looks like there's fluid building up (almost like a blister). when i push my foreskin back, it returns to normal after a few hours or a day max! So i think there's nothin to worry bout!
I am hoping somebody can tell me how to prevent this and how i can keep my foreskin back without this happening?
please help
