Ever since i was younger, i have been boy crazy. I can recall have crushes on boys as early as 4 and 5. I am the biggest girly girl; i cheerlead, do gymnastics, love doing hair and makeup, etc. I've had countless amounts of crushes on boys my whole life up until now, and i am 17. This summer i fell in love with this guy but he lives far away and i can't see him often. I always love getting ready and looking good for boys. I go to an all girls school, and have never once looked at girls sexually in any way. I watched porn however, and now i can't get all these naked images out of my head. Ive always been sexually turned on by guys, but now my mind won't stop picturing girls naked and its grossing me out. I have had horrible anxiety and purely obsessional OCD the last 3 months and this is my most recent obsession. I have been so depressed and anxiety ridden lately because of these thoughts. I am such a romantic and would always dream about having the perfect boyfriend and now these thoughts about girls are all that occupy my mind and they leaving me feeling so depressed. I don't understand why I'm feeling this way when a week ago i was crying over some guy. I would never act on any sexual thought with a girl because it kind of grosses me out. Can someone randomly just change sexuality? Is this just homosexual OCD? Please help because these thoughts are occupying and ruining my life and i can't take it anymore:(
