thanks for sharing ur problem
see u ve to judge whether ur boy friend is truely loving u or not???
or is its his perversion or obcession????
whom he loves, discussing sex related things or wanting to have sex with her always is a matter of great concern
future of ur love is also questionable in that case
both of u need to have a PSYCHIATRIC COUNSELLING
again sex before marriage has certain advantages
u can assess ur partner by this way but obviously it ll not be against ur will
so do have a counselling properly
that ll remove ur rigidity and his obcession
