You've asked an unanswerable question...so all I can offer is some interesting reading to become better informed on the topic.
Most people associate erectile function with neurovascular bundle "disruptions," but you are correct that the orgasm itself is just as commonly affected by nerve-sparing or non-nerve sparing RP. Tewari published an interesting report on robotically assisted RP (compared to
open RP) in 2011
HERE. I love this line:
"Orgasm is a compelling, brief event..."You didn't mention you age (which was an important factor), but here was an important finding:
"In men ≤60 years of age, a significantly higher percentage of patients who underwent bilateral nerve sparing had orgasm postoperatively (92.9% vs 83.3% vs 65.4%, P < 0.001)...when compared with patients who had unilateral nerve‐sparing and non‐nerve‐sparing surgery, respectively." Significant decline in orgasm for men who had non-nerve sparing surgery.
Note that the use of PDE5i (Viagra, Cialis, etc) affect the ability to have erection, but not orgasm.
Here's the first paragraph from the Discussion section:
"Orgasm is a compelling, brief event that is an integration of cognitive, emotional, somatic, visceral and neural processes 14. It is a combination of physiological and psychological changes that occur coincident with ejaculation in men. Physiological changes during orgasm are tachycardia, sweating, muscle contraction and rhythmic contraction of the ejaculatory apparatus 15, whereas psychological changes include an altered state of consciousness, release of tension and emotional euphoria. As the ejaculatory apparatus (prostate, seminal vesicles and ejaculatory ducts) is removed at RP, the patients subsequently cannot emit sperm and so have ‘dry ejaculations’16. Other changes in orgasm such as decreased intensity, anorgasmia and dysorgasmia have also been reported in patients after RP 16-18. The consistency, quality and satisfaction of orgasm can significantly affect quality of life 16, 17, 19. Therefore, any alteration in orgasm, especially its absence, is associated with significant reductions in emotional and physical satisfaction, which may in turn lead to avoidance of sexual activity and disharmony in intimate relationships 12."
