Havelock Ellis is known who created the volumes of the
psychology of sex and these volumes are in series.
Also the havelock challenged the old and also the common view
to shape them into the new perspective and to avoid the negative
stigmatism such as:1) In women there is the sexual desires which
make them healthy 2) Also the sexual problem can arise due to
psychology rather than physically
Alfred Kinsey:
Because of the studies made by the Alfred Kinsey who has
conducted the large studies on sexual behaviour the subject of the
sex has been taken as the scientific study in the field of
research.
Due to this the upcoming generation can openly take part and
can openly talk on the sex related matters or the sexual
behaviour.
