Is there a physical difference between having an orgasm while fucking vs when you jerk off to porn? Now obviously sex is better, but I'm trying to abstain from porn and orgasms alltogether unless it's having sex. Usually after porn I feel like human trash vs when having sex I feel like a fucking tiger that I am, but orgasm is the same.

Is the difference phisiological or is it purely psychological?

I know the mechanisms behind it, porn shame and animalistic sex and all that, wanted to know what your oppinion is on the matter.
