Idk about that though.
My taste in porn shifted to IR about 10 years ago after having actively avoided it before. Never really thought about it but had a huge library which basically only consisted of BBC-Stuff and I also liked the cuckoldsessions and cumeatingcuckolds stuff (just nothing of the "bi-stuff", where the guy'd suck dick they sometimes had in it). It only struck me, what audience this porn was mostly for, when cuckoldsessions released a scene with Ash Hollywood in which there was no cuck, but she directly adressed the viewer instead. As I'd had my last GF and sexual experiences shortly before I escalated to that kind of porn, I got real anxiety when I realised that there are actually lots of people, who do the stuff I watched IRL and my fear of becoming like that too lowkey developed into some kind of OCD-like mental disorder where I'd constantly check if fantasys of doing this stuff IRL myself might turn me on. The halfbaked "nofap"-theories on the internet and likeminded people going through the same shit circlejerking their bro-science-fueled anxiety on Reddit only made it worse.
Thankfully I was eventually able to leave this behind me and realised that it's just porn for me.
Now here I am many years (and 10+ women I slept with) later and can definitely say that my taste in porn doesn't have the slightest impact on my real sexlife.I still watch the same kind of porn and it always fucking gets me going, but IRL my sexual desires and actions couldn't be more different and the idea of my gf fucking someone else - no matter what skincolor, couldn't be any further beyond me, so I'd say keep watching your stuff if it makes you happy. Just store it away safely if you download it like I do - because I'd still fucking hang myself, if anyone knew what fucked up shit gets me going when I jack off.
