Anybody else struggle with impulse control when it comes to substances? :-(

When it comes to soocd exposures, that sometimes means engaging in triggering things like sex and intimacy with my partner, but I worry that I am sometimes also being compulsive like wanting to be intimate to see how it makes me feel, check my feelings, sensations, emotions etc. and then at that point how can I really do the exposure? Idk I’ve just been struggling so much with this theme lately. I feel like a fraud most of the time and the thoughts convince me I am deeply in denial, constant loop.

Anyone struggle with this with having ocd?

I have the thought of what if I lose control and do something out of my control like scream for no reason or yelling in a store or just blurting stuff out that’s not in my control and it causes so much anxiety and causes me to feel weird. I always think I’m on the edge of losing control of myself and it’s exhausting living like this. Any tips?
