My apologies in advance if this is the wrong forum to post it. I'm not exactly sure where else to turn to for advice, as this seems to be a 'laughable' issue (please don't judge), but is not close to serious enough for seeking 'professional help'.

Long story short: sexual violence, rape, strong sex scenes or cross-species animal sex upset me beyond measure. In fictional movies, real porn, TV series, etc. it doesn't matter.

Even if I read about a movie containing such scenes, without ever seeing it, if someone I know has seen it, it will get stuck in my head and will stay with me for weeks. Lately whenever I read "50 Shades of Grey" I need to be alone, control my breath and focus on something happy to calm me down. I project these negative feelings also on the people who watch these kinds of things. This has caused me to grow feelings of resentment towards my partner, who enjoys watching certain movies that contain sexual violence (American History X, 50 Shades of Grey, etc.) or, for example, Saw-based porn because it's 'funny'.

I'd like to self-analyse and get better, but I can't find anyone or anywhere on the internet a similar issue. I've had this for as long as I can remember, even as a kid. I don't know what to do with these feelings. Whether to accept or ignore or face it or learn to avoid the triggers or what... I don't even know where it comes from.

The sex can be male-on-female or male-on-male, both trigger me.

I'm fine with blood, gore and violence within limits. That's not an issue.

I'm 24 years old, male, gay, monogamously partnered, healthy personal sex life. Had an alcohol & drug addiction for 3 years, so during this period this issue never really bothered me.

Hope someone could point me in the right direction for self-healing before I destroy my relationships over this... Thank you in advance.
