Biologically speaking, having an orgasm is way more like having a 'good' seizure than it is just a peak of excitement.

Orgasm Onset as a Threshold Transition: When Bottom-Up Signals Override Control Without Collapse
PsyArXiv · njs3z_v1
The Takeaway
Researchers found that the climax of sexual arousal occurs at a specific "edge of instability" where the brain's internal signals briefly take over conscious control. It redefines a universal human experience as a precise mathematical transition.
From the abstract
Masters and Johnson (1966) distinguished plateau from orgasm as a qualitative transition marked by loss of voluntary control and reflexive discharge rather than gradual intensification of arousal. However, the neural mechanism underlying this abrupt shift remains unclear. This paper proposes that orgasm onset is a threshold transition defined by a calibrated inversion of hierarchical control, in which bottom-up interoceptive signals transiently dominate over top-down inhibitory regulation while
