Yes, because we can (although not all time) have another stimulus by serotonin and oxytocin, the passion neurotransmitter (and not only by endorphins and dopamine). This is why prostitutes are so problematic for incels: timed sex, limited emotions, lack of involvement, etc. The brain can't feel much difference in cooming with fap or sex with an unwanted person, but does for oneitis and highly attractive persons. Have you ever feel a female smell, even though faked with perfume and far away, and instantly got goosebumps with a pleasurable pain in the heart (occasioned by endorphin as a trigger and other endogenous opioids) after imagining at least touching that girl? That's psychical attraction, something that masturbation can't emulate in the same intensity.
