It has been said that jouissance is 'drained' from the body throughout life, leading to the calm of old age Pleasure is not a controlled state nor is any feeling as it is. I dont know why to be interested about suffering IN pleasure. In his seminar "The Other Side of Psychoanalysis" (1969-1970) Lacan introduced the concept of surplus-jouissance (French 'plus-de-jouir') inspired by Marx's concept of surplus-value: objet petit a is the excess of jouissance which has no use value, and which persists for the mere sake of jouissance.
In "Encore" (1972-1973) Lacan states that jouissance is essentially phallic. That is, insofar as jouissance is sexual it is phallic, meaning that it does not relate to the Other as such. Lacan admits, however, that there is a specifically
feminine jouissance, a supplementary jouissance, which is beyond the phallus, a jouissance of the Other. This feminine ouissance is ineffable, for women experience it but know nothing about it.
