Okay, some things my hocd ( I hope! ) has been scaring me with recently?!

1. That I became increasingly interested in gay people right before this happened.

This is partially true. I got tumblr and it's all very gay aha on there. I also started watching a tv programme of which there was a gay ship, who I read fanfiction about (boys, not girls). I do remember once or twice searching people on Facebook and trying to work out if they were lesbians from some rumour or comment. This is the one that stresses me out the most. I always do weird searches on Facebook when I'm bored, I generally have a few people I'm interested in and they change around, but I always thought 'stalking' people of Facebook was normal. All my friends do it, but I'm worrying that maybe I did it too much or something? I read on a LGBT forum (I've been spending loads of time there to try to give me reassurance, I know it's bad!) that some people "become mysteriously interested in homosexuality right before they realise they are homosexual themselves". This scares me so much I want to cry. I wasn't really mysteriously interested but was I? Help

2. I have had the occasional same sex fantasy.

Why? Why? Why did i do this? Having said that, it was like one in one hundred opposite sex fantasies, but is it normal or an indicator of homosexuality? Problem is, I can't seem to remember my straight fantasies and it keeps telling me they never happened or very rarely happened. I know they happened frequently but did I? Grrr

I know this sounds like I'm lesbian because I haven't tried to prove to you that I'm straight but please can someone maybe explain or give their opinions on things? People with similar things to this that post on LGBT forums are always told they're lesbian/bi and it scares me so much!! I've been doing so well but these things just keep going round and round. Has anyone else done/thought these things or can give be some help as to whether try are substantial evidence towards homosexuality or ocd blowing things out of proportion?

Thankyou
