Does anyone have ocd revolving around the fear of puking? What do you do to deal with it?

I’ve been feeling the urge to avoid intimacy or purposefully engage (for reassurance that I won’t give into a compulsion) because of intrusive thoughts and fear that I’ll “check/test” my reactions. My OCD is making me so scared that I’ll purposefully think of a child and try to see if I like it. It’s so complicated but I guess I’m mentally checking if I would mentally check during intimacy. I’ve even envisioned myself checking and it’s making me so nauseous. I know it’s a compulsion like any other but the sound of “touching yourself to the thought of a child” sounds atrocious and vile. I’m terrified I’ll automatically start checking next time I am being intimate. I truly feel so worried. If anyone has gone through something similar, I’d appreciate hearing your experience. Or if anyone has any advice?

Recently, I’ve been struggling a ton with what I eat/put into my body? I’m a first year college student with a few different health issues (including IBS), and lately it’s been hard for me to find food on campus that doesn’t upset my stomach. I also have pretty severe emetophobia, and feel extremely anxious when I feel sick. The ironic thing is that being anxious makes me feel even worse, so I end up sticking myself in an impossible loophole. My OCD has taken hold of these fears over the past few months, and it’s been such a struggle. Especially since people have been getting food poisoning from various dining halls on my campus lately. My OCD has gotten so bad that sometimes I’m too afraid to eat food other than what I buy myself. I feel so trapped. I don’t want my OCD to affect my physical health or prevent me from eating, bc I love eating!! It’s the fear of getting sick that’s the problem. And it’s even harder when everything is so unfamiliar. Just wondering if anyone could relate. Advice is appreciated!

Does anyone else get fixated on one “topic” with their ocd?? like for me trains and guns are mine. like i’m scared of trains and im scared to be around guns because that’s what triggers my ocd and makes me convince me that that is the way to go. i literally worry myself into thinking im going to sh*t myself when i don’t even have a gun but my ocd convinces me. idk if im explaining it good, but its a real struggle. just need some tips & advice
