Im scared im asexual

I am a 21(female). I have only ever kissed one guy and it was horrible and I cried after. I stress about my sexuality constantly. I only want to be straight and know I want to end up with a man, but picturing it stressed me out and I am so scared to kiss a guy I think about it and get so stressed and cry immediately. I have severe intrusive thoughts about kissing everyone my teachers my best friends and it creeps me out and then I go down a rabbit hole of sexual orientation ocd! If anyone has any tips that might help that would be great. Again I don’t want or think I am gay but being so scared to be intimate with a man starts me down a spiral.

Hi I just have a few questions! (Im 14 btw) Okay so basically I’m really worried I’ll become a pedo/I already am and I don’t know it yet. I’m also really scared if I SA someone, even tho I don’t want to and I’d never do something like that but I feel like this part of me is saying that I will and it’s really scaring me. I feel so alone and I’m so scared I’m a bad person on the inside and this isn’t ocd and I’m gonna unleash hell on this earth I’m so scared. I’ll get a thought like if I’m walking past someone random it will be like “What if you sa them?” And it scares me so bad I feel horrible for thinking that. Is this apart of it? I feel like I’m always fixated on the topic of sa to check if I would do something like that, I don’t know anymore I just feel like a bad person (btw I have not done anything like that to anyone!)

Why are things so real the first time they’re in my mind and then when I think about it later it’s easier for me to be like wtf?? I was watching a movie earlier and the young girl had developed more in the chest area than the last movie and I felt the desire to check her out so I did. Then later I let myself imagine her having sex and I liked it. But now looking back I’m like ew. The boys in the movie have also developed as the movie went on and I couldn’t help but think that in their real life they’ve probably woken up to boners and s*men and stuff. And looking back it’s just ugh. Idk if it’s sexual relevance but I genuinely let myself indulge in these thoughts and groinal responses and I remember thinking to myself I don’t want to be attracted to little kids and how do I stop myself (everyone has attractive qualities so in younger boys I see man like qualities). Idk I need help. I wouldn’t type this out if I truly believe I was messed up but I’m still scared
