"sex" is a social construct.
the brain releases the same levels of serotonin and dopamine based on the level of arousal during climax, this has nothing to do with "love making" or "passion" or "intimacy" unless your intellect is so low it lacks critical thinking and cognitive creativity.
stimulating your penis or clitoris is all that matters, looking at, or thinking, or imagining things while doing that is what effects the levels your brain will create and release.
you can mimic the adrenaline and "intensity" very easily in the comfort of your bed alone with the porn of your choice, even "porn" is subjective, it can be non nude or a still image that you create a scenario around, or a live action porn scene that stimulates something in you allowing your brain to then add on to it.
there's endless scenarios, all of which cost nothing and result in the same level of satisfaction
