Please help me to understand him

This is about my doctor(he is already married).On the very first visit to him he treated me normally (for an ear infection).But he asked me to make more visits to him.He ordered me to do some checkups that is completely irrelevant.(i have got to know about this from another experienced Doctor).he keeps his hand on my back while (on the very first day he didn't do that) examining my ear and hitting his knee to my knee.
one day he forcefully pulled me to him while spreading his legs.I was so upset.And then told me some unwanted things.
He asked me several questions about my father(he knows my father very well,he just wants to know whether my father is actually my father or father in law.But I have ignored it.after examining my ear he again asked me directly about my maritial status.He also asked about the regularity of my periods and whether I am getting painful periods.

4 months after the above incidents I went him for another illness,he warmly welcome us and asked me about my ear infection(he refferred me to another doctor).He again examined my ear even he can remember the ear exactly which was suffered by the infection (my right ear).
