do i have Paraphimosis and/or phimosis?

i'm 19, still a virgin, new at this, uncircumcized Penis, (when penis not erect:Skin covers the head, and when penise erected:skin still covers the head.) when i get a full erection, the extra skin does not go over the head onto the shaft. i tried manually pulling the skin down but achieved no succes, it was tight and a little painful. while doing so a 1/4 of the head was visible. however, when my penis is not fully erect or when it's semi erect, i can pull the skin past the head onto the shaft. however the skin bunches up behind the head and it feels a little tight/awkword. it feels as though i'm loosing circulation and my penise starts to shrink, it's a little difficult to have an erection as well. the extra skin can come back to it's original status of covering the head, but i have to manually do it. it won't do it automatically.
rolling skin forward while in warm bath onto two fingers gently pulling apart to stretch 'ridged band' then reverse roll back to tightest point and holdin for longer each time 'skin only stretches when kept under tension for extended periods of time.retracting every time you urinate and using cortico-steroid creams also are effective.
