Have i developed ocd. Than stopped it!

Hello, I was doing prone masturbation since all my life i am 19 now...one day in October 2016 i came across a website named healthy strokes that say prone masturbation is harmful for my penis health ..than on 30 th octomber 2016 i tried for first time hand masturbation i was not able to reach orgasm and then on same day i got jerk in head and black out eye and then i rested for some time....then i started doing prone masturbation again but i was worried about the event that happened...and during the same time i had a dream that i my penis was cut and people took me to hospital.... now i am experiencing that penis is getting stuck on the object i see like ( penis is being scratched by razor, penis is cut by something, my charger is scrating penis) but there are less episodes of that may be once a day sometime...that too when i am alone.....during the octomeber period i took ssri and antidepressant one dose and than stopped it
