Kinsey also went to some lengths to ascertain the "age at first response to orgasm." We have already indicated the youngest orgasms for both girls and boys.

In particular, Kinsey notes three women who had not reached their first orgasm until they were between forty-eight and fifty years of age. It should be stressed however that lack of orgasm is not synonymous with lack of sexual response, and that a very satisfying sex-life can coexist with lack of orgasm.
