The "Deep Spot" orgasm mentioned in that article would appear to be associated with a deep nerve complex being stimulated, but as I understand it, female anatomy apparently has
two deep vaginal nerve clusters in pockets known as the anterior fornix and the posterior fornix on either side of the cervix.
Under the circumstances it would seem likely that there is the possibility for two distinct "Deep Spot" orgasms.
Being a mere male, I can only theorise about this - perhaps
DiTo can enlighten us deficient beings from her own vast experience?
