I have ocd about if I'm gay or not and worry about it all the time, its terrible. I test myself to make myself feel better and see if I'm really gay or not. I look up naked guy pictures and I don't get aroused, no matter how many naked guys i see. I dont get erect or horny. I test myself on gay porn too and I dont get erect. When I see gay porn, I automatically get anxiety and it makes my heart beat fast. I dont enjoy watching it but i test my reaction to see if im gay. What usually happens is my penis actually shrinks and tenses up, like if I was in a cold shower. Does that mean I'm aroused? If I see naked guys and my penis actually shrinks and tenses up? Then I'll look up straight porn right after to see if I get aroused by that and I get an erection immediately, also with lesbian porn. Please give me your opinion, it might sound stupid but I seriously have so much stress over this, thanks And also, I've never had a crush on a guy, only girls. I had a girlfriend at one point and was so into her, and was aroused everytime we touched. But I havent been able to have a real crush on a girl since I've started worrying myself with this.
First step is to not worry at all. You're attracted to whom you're attracted to. Looking at porn doesn't really indicate one thing or another. You seem really worried that you might be gay. I'd stop stressing over it and let your body figure it out. You shouldn't "test" yourself, instead just go with the flow. Feel like watching a straight porn? Go for it. Feeling a bit curious? Go for it. Don't try and pin a label on yourself so fast.
I use to watch a lot of gay porn, but now I watch straight porn a lot. I'm not sure what caused this change, but heterosexual sex seems so much more amazing. Maybe it's becusse I don't find sex with a guy that amazing. Void Puppy brings up a great point: you're attracted to whom your attracted to. It definitely takes time to accept yourself as who you are, not necessarily in terms of labels, but as an individual. I'm still struggling with this, so you aren't alone.
Why are you so worried about being gay? If you're attracted to women, had crushes on women, and don't find guys attractive that way, then you're probably leaning way more to straight.
You're putting too much head into this thing. First, you need to relax. If you enjoy being with girls, you can be with girls, and call yourself whatever you want. It's all about being comfortable and happy with the things you do. I doesn't matter if you get aroused by something. Gay or straight. Actually that doesn't define your sexuality at all... Please don't try to lock yourself in a box, you'll find the object of your desire one day and, either, male or female, you'll be happy and that's it. Enjoy life and don't worry!
