I'm going to be 29 this month and I was exposed (by my own volition) to plenty of porn by being left alone on the computer when I was way, way young. Fortunately wasn't exposed to a lot of crazy stuff, just one puke video and the infamous 'two girls one cup' (which did not faze me because somehow I watched it and decided it was totally fake and they were makin play-dough or something come out of their asses, IIRC). I am curious how it affected me...my first girlfriend/sex partner for around a year when I was also a minor..I feel I had too high expectations and it did color my ideas in a not so acceptable light...nothing extreme though.
Overall though I can't say I have a fuckload of weird fetishes, definitely like to eat the ass IRL (I've been very fortunate in that regard, 100% clean and good smelling orifices) and for sure enjoy porn that portrays that act. I like to eat pussy, but I don't like to watch men eat pussy on camera. I like seeing girls get cum on, generally the face (only if she is into it) not the buttcheeks etc. because I get off mad to watching a woman in pleasure. Amateur porn is definitely the best because I see much more authentic reactions and such.
The gals I look for in porn are definitely the type I'm attracted to IRL - not too thick or too skinny, & generally brown as opposed to white or black, but mostly about the nuanced beauty of the individual than the exact type or skin color.. But, generally I'm burnt out on blonde gals (slept with too many in high school/college) and used to be more into 'redheads' but these days I'm not even into the white girl 'aesthetic' that much, in porn or IRL.
But following with what
@MFB said about the 'mental reserves' or however he worded it - I'd say the best way I get off if I'm masturbating is to imagine a girl I *have* been with along with a girl I have regretted not hooking up with, together in a threesome, and everyone getting some action simultaneously....I mean I like best threesome porn with two girls and a guy and I think it mad weird with one of the girls simply observing labeled "threesome"....this specific fantasy works for me way better than any manufactured porn.
I'm no stranger to hooking up with people with penises IRL but never got into 'gay' porn. Transgender folk moreso, the female asthetic and a big ol dick, cool, but I can't recall masturbating to it - more just like "I'm lost in my mind and abusing the internet". Again, dark-ish Latina is the preference, but it's more about the nuanced beauty of a person than a demographic. Although IRL I've only really enjoyed being with black dudes and brown(er) trans-folk.
I've only been in one threesome IRL (with two gals) and only have been with one girl who wanted me to cum on her face/chest - other than that my porn preferences very much reflect my IRL preferences/types of girls I like to date or have dated.
Hopefully you found this intimate post entertaining !
